Replace heat sink or fan (or both)?

Would replacing the heat sink or fan (or both) help to to reduce the temperature of a really warm powerbook or is it hopeless?

never seen "temperature guidelines" in any sources - either Apple service manuals ot otherwise.
"official position" is that laptop is supposed to run hot sometimes.
as a guess, replacing fan/heatsink is probably not worthwhile, especially since hot temps could be caused by different components, such as hard drive, RAM, AirPort card etc.

G3 Pismo processor replacement - no heat sink bracket???

Hi there
This is kind of related to a previous and still running thread to do with my dead pismo but I thought I would start a separate thread for this problem. I just got a replacement processor for my Pismo but there doesnt seem to be anywhere to screw the two screws in from the heat sink that will sit above it - i have seen in other photos that there is usually a round plastic bracket with two screw holes that sits on top of the processor? Any advice? or is different for certain processors?
thanks

troy:
are any of the later G4 Powerbook processors interchangable with the Pismo?
Unfortunately, no Would have been nice, though.
a G4 processor and a gig of RAM I know the Pis would be a great back-up
There are several threads in this forum which discuss processor upgrade. This one traces my own decision making process. As you will note in the thread, this is not an inexpensive upgrade. In my case it was an easy decision since this is my primary computer. I recommend getting your computer going and see it runs for you. At later stage, if you decide to go this route, you can research the different threads, and, maybe, even post one of your own. There are many Pismo owners who have upgraded and would love to share their stories.
can you recommend G4 processors available for the Pismo
Mine is by Wegenermedia, and although it works fine and my experience with Wegener was not bad, others have had very negative experiences. I hesitate to recommend Wegener. Look at the others mentioned in the thread. Give yourself some time to research and think about it.
Good luck.

Expected cost to replace macbook heat sink

Does anyone know how much it would cost have have apple replace the heat sink in my early 2008 model macbook? The warranty is obviously gone, but other than the fact that it overheats, the computer is in fine condition. here are my basic specs.
2008 model mac book (black)
2.4 ghz intel core 2 duo prcessor
2 gb 667 MHz DDR2 SDRAM (upgraded from 2 GB by user)
Intel GMA X3100 144 mb graphics
running lion OSX
I don't trust myself with opening up the main casing, I barely trusted myself upgrading the RAM.
Approx cost anyone?

The heat sink and fan are an assembly. What makes you think there's a problem with the heat sink specifically? Have you reset the SMC?
Laptops with a battery you can remove
Shut down the computer.
Disconnect the MagSafe power adapter from the computer, if it's connected.
Remove the battery.
Press and hold the power button for 5 seconds.
Release the power button.
Reconnect the battery and MagSafe power adapter.
Press the power button to turn on the computer.

MSI R6950 Twin Frozr III Power Edition – Replacement Heat Sink?

Hello,
Does anyone know of a good 3rd party heat sink that will definitely fit this non reference card? We all know that manufactures such has Artic, Thermalright and Prolimatech make such heat sinks, but of course they are for reference cards. I'm sure you can understand that I don't want to make any expensive mistakes!
Thanks,
Krutish.

Thanks for the reply flobelix.
My main concern was the amount of decibels this card produced when pushed, not its thermal properties. Under high stress the card would peak at 80-85c with a fan speed of anywhere around 80-100%. Normal gaming temps would be around 65c-75c depending on game, or gaming environment, with matching fan speeds. That is why I was looking for a replacement, the temps were within the manufactures tolerances, even if a little high, but the db's were well outside of mine!
However, the situation as changed somewhat. While messing around inside the case trying to improve airflow I accidentally touched the heat-sink assembly, and upon doing so the fan instantly roared to 100% and the temps started to shoot up. I wiggled the assembly again and the fan and temps dropped back! So it seemed like the heat-sink was lose! I removed the card and tightened the screws a little, this solved the problem in regards to the temp/fan shooting up, but the temps were still high!
The next step was to completely remove the heat-sink, give it a good clean and replace the thermal compound in the hope that this would solve the noise/heat problem. It was at this point that I spotted the problem! The GPU was absolutely caked in thermal compound, so much so that all of the resistors around the GPU were also covered in thermal grease, (Don't these guys know less is better?) good job they hadn't used a metal based thermal compound, that could have wrecked the card!
Anyway, I removed the mess and used TIM-clean to dissolve what was left and finished the clean up with isopropanol. I applied a small amount of compound, replaced the heat-sink and Bobs your uncle! Max loads so far, GPU 64c – Fan speed 55%... That I can live with!
So there you have it, this card as been noisy and running hot from the day I brought it, but I didn’t know any better, I've never seen or heard a MSI R6950 in action before, now I have!

Oh almost forgot... i heard off Artic, they recommend the Twin Turbo II, Xtreme II or the Xtreme III for this card!

How to make 260 gtx 55nm VRM custom heat sink

Warning: This will void your warranty
The caveat above added by Mike, Forum Administrator
How to Create a Custom 260 GTX 55nm VRM Heat Sink
Introduction: This guide was created to show how you can make a custom VRM heat sink from the stock heat sink to be used with an aftermarket cooler.
Reason: Many aftermarket companies, such as Thermalright and Arctic, fail to provide a good VRM heat sink for the 55nm 200 series GTX’s. The solution often involves poorly sticking thermal tape or no solution at all, such as the Arctic cooler, which states it’s ok to leave the 260 GTX 55nm VRM chips uncovered. To leave the VRM chipset uncovered maybe ok for stock clocked cards but what about an over clocked card or an enthusiast trying to push the performance envelope? That is after all, what these aftermarket cooling solutions are all about; especially the Arctic cooler which can cool up to 250 watts! Fortunately the solution is very easy and should take you no more than 10 to 15 minutes to address.
Use: To create a custom made VRM heat sink to be used with an aftermarket cooling solution such as the Arctic cooler and Thermalright cooler.
Tools:
Dremel, with metal cutting wheel and sanding wheel.
Thermal Pads, which you can buy in sheets from any performance pc store and should be 1.0 mm in thickness.
Philips Screw Driver, very small size would be ideal.
Before we begin I’d like to remind you that removing or tampering with the stock heat sink will more than likely void your warranty. This guide was also constructed assuming an aftermarket cooler will be installed. The card used in this guide is a MSI 260 GTX 55nm with reference PCB design (REV 1) but will also work with other 200 series GTX cards. When working on any electronic device, always make sure you are well grounded!!!
Step 1: Remove the screws with the springs only from the back side of the graphics card as shown in figure 1A. There is a total of 13 spring screws that need to be removed. Check to make sure that your card does not have two small additional securing screws which are located on the exhaust side of your graphics card with your DVI ports. If your card does contain these additional screws, remove them before continuing on to step 2.
Step 2: Gently work the card from the heat sink. NOTE: Do NOT force or pry heavily, you will damage your card. It may take a little caressing depending on how much poor quality thermal putty was used from the manufacturer.
Step 3: Remove the fan power connector from the fan power port as shown in figure 2A.
Step 4: Remove and discard all the old thermal pads. You should never re-use thermal pads and especially not the low quality manufacturer ones! NOTE: keep in mind the location of the VRM thermal pads since you will be making replacements.
Step 5: Clean off the voltage regulator chips with a tissue or with a soft eraser as instructed by Arctic. Personally I use a tissue very lightly dipped in alcohol to clean the surface of the chips. The voltage regulator chips for the 260 GTX 55nm are shown in figure 3A. NOTE: I will not be covering the cleaning of the GPU or Ram since it does not pertain to the VRM heat sink.
Step 6: Flip the heat sink so you are looking at the bottom where the thermal pads were attached. There are 6 very little screws which need to be removed from the assembly. Figure 4A shows the location of the screws attaching the plastic shroud assembly. Once they are removed gently pry the plastic shroud off and set it aside.
Step 7: Now turn the heat sink over and remove the 4 black screws from the top side of the heat sink. The fan should come off freely and set that aside as well. Your heat sink should look like figure 5A.
Step 8: Now we are ready to begin cutting the stock heat sink. With a sharpie draw a black as shown in figure 6A. This will give you a marker to follow when cutting.
Step 9: Attach the metal cutting wheel to the dremel and begin cutting across the black line. Danger: ALWAYS wear eye protection when cutting a metal object or any object. The metal is very soft and not much force is needed to cut it. Try not to damage the mounting holes when cutting (figure 6A). You may need to lightly sand the cut edge depending on how rough or jagged it is after cutting. When you’re done you should have a piece as shown in figure 7A. This will be your VRM heat sink. Important: MAKE SURE you clean the heat sink well and remove all metal particles. Also allow the heat sink to dry well before installing!!
Step 10: Next cut the new thermal pads to the shape of your VRM chips. It should look like figure 8A when you are finished.
Step 11: Gently place the heat sink into place and attach the screws. When you are done it should look like figure 9A.
Congratulations on your custom made VRM heat sink. The great thing is that it never has the risk of falling off, such as thermal taped ones, and can be removed and installed as many times as you wish. It also does not contain thermal adhesives which also do not facilitate removal as well. The stock spring screws will also insure secure contact between the VRM chips and the sink. The custom heat sink comes with nicely built in fins and much better cooling performance then individual dinky VRM heat sinks provided from the Arctic or Thermalright coolers.
p.s. It is possible to put old heat sink back on the card since each section has its own mounting screws but I would not recommend this unless absolutely necessary.

I'm running a corsair 750 watt PSU
Q660
Gigabyte g31 motherboard
1TB WD Hard drive
OCZ 1066mhz of ram
And I recently swapped the lighting with a gtx 260 and see what would happen in the same system. The GTX260 ran games smoothly, and would run furmark fine with the newest nvidia drivers. Swap back the gtx 275 lightning, and games are really slow and choppy especially when you add any kind of AA. The FPS is literally cut in half when I switched to the msi gtx 275. I think it's safe to say that the GTX275 is defective.

Cleaning heat sink on Macbook Pro Retina after liquid spill... HELP!

Hello all...
My wonderful boyfriend spilled about 3-4 tablespoons of orange juice on my Macbook Pro Retina (15in) on Thursday. Right over the left speaker and onto the ESC, ~, brightness up and down, 1, 2, 3, TAB, Q, W, Caps Lock, and A key. It also dripped down and got into the vent. I immediately (like within 1 second) grabbed it and turned it upside down, and wiped it up while holding it upside down. I then turned it off and held it upside down for some time, and let it sit open and off after that. I turned it back on the next day and had no apparent issues. (However today some of the keys have been "crunchy", so I think I better clean them...)
I couldn't get it to the Apple store until yesterday because of Hurricane Sandy and not having power or anything. I had the genius check it out. He could only take off the back without having to charge me anything and he said that none of the liquid sensors were tripped in the back of the computer but that there was some dried up orange juice in the heat sink (but apparently not really anywhere else which he said makes me the luckiest person in the world). He took a photo on his phone and showed me... just some residue and orange juice that looked "dried up" in like 5 or 6 of the vents. He said that I could try to clean it myslf with alchohol wipes and a toothpick at my own risk. But I am very nervous as I am not exactly tech savvy... I watched videos on how to take the back off, but the part about disconnecting the battery and all gets me nervous. My question is, do I have to disconnect the battery to just gently clean up the heat sink with a little toothpick and alchohol wipes? Do I have to ground myself? What do I do?
Also, how necessary do you think it is to even clean it up? Could the heat sink need to be replaced in the future from this? Is it really a big deal? I'm looking for honest answers, since I felt like the genuis guy had too much liabality to say anything to me about anything.
Unrelated, what are the chances that liquid got through the keyboard to anything more sensitive to liquid? The genius couldnt really give me an answer. I have noticed just as I am typing now that sometimes it seems that the cursor of where I am typing will just jump back to the end of the previous line when I hit the Caps Lock key... it's very strange and I'm getting agita just thinking about it. Could that be a problem with just my keys getting stuck somewhere or a bigger problem with hardware being damaged... help and THANK YOU!

When i start any game the CPU goes up to 90° in 2 minutes and the computer shutdown after at least 5 min.
I found a solution. after a lot of research i checked that my fans are working on the minimum means at 2000 rpm even when the games are on. so i install it a software called smcFancontrol that u can control ur fan speed and i make it up to 4000 pm (you can do it with iStat menu too) and i tested my computer. I Have been playing on my macbook pro since this morning and there is no problem of overheat or shutdown.
Is it normal that we need to change the fan configuration or control to play a game that was working fine before.?
for cooling my machine i have a mStand Rain design http://www.raindesigninc.com/pic_high%20res/mstand_macbookpro_keyboard_perspecti ve_unibody.jpg

Pismo CPU upgrades/heat sink

Does anyone know if the 400 mhz heatsink and 500 mhz heatsink are interchangeable?
PowerMac G4 MDD 1.25 Ghz, PowerBook G3 Pismo 400, Newton 2100, iPod Photo 30 gb Mac OS X (10.3.9)

Hi Gerry:
Are you replacing just the heat sink, or the entire processor daughter-card? If the heat sink and tube only, yes, they are interchangeable. Be sure you apply a thin, even layer of thermal compound on the processor after removal of the old heat sink and before installation of the new.
Good luck.

Best cleaning steps for g4 processor and heat sink?

I just pick up a dual 800 quicksilver cpu. What is the least expensive/best way to clean the die surfaces as well as the heat sink surfaces? Also does anyone know a link showing stable higher than originally rated speeds?

Hi pheidius-
The surface description is odd- I would expect it to be smooth (as all heatsink surfaces I have seen).
You may be correct on the thermal pad. It would be the only logical explanation..... I've never really "dissected" a thermal pad before- just scraped them off and tossed 'em.
If it is a thermal pad, you may have clearance problems with just thermal compound. This is, of course, dependant on the thickness of the previous pad......Just check the heatsink and it's contact on the processor after you have finished cleaning the thermal pad from the heatsink. It should be obvious if there will be clearance problems.
Recommended removal proceedure for a thermal pad is to use a plastic card (like a credit card) or a plastic putty knife.
When replacing thermal pads, after the old is completely removed, the heatsink surface needs to be heated until hot to the touch (use a heat gun), and then apply the new pad, pushing the pad on firmly and evenly.
Note: When using thermal pads, wait until the heatsink and pad are cool before removing the protective paper and installing on the processors.
If you end up using thermal compound, carefully apply the compound. Getting sloppy, and applying too much, especially with Arctic Silver, can cause problems. The compound is not just thermally conductive.......it is also electrically conductive.
Back to the overclocking question- This article may be of interest.

Wind Box DC100 change fan/heat sink

Hi,
I just bought the MSI Wind Box DC100 with the AMD E-450 APU, which is nice and all. But the fan on this thing is so insanely noisy, I have had a look inside (I know, warranty voided and all that) and everything looks very proprietary. I am looking to replace the fan, or the whole heat sink including fan if possible. Does anyone know of any solution to that? I have not found any standard coolers that has the same form factor as the one used in DC100.

I completely agree with the first post; the fan in the Wind Box DC100 is insanely noisy.
I bought this tiny PC for using as a mediacenter, but the fan is always running and has a high pitch that it's impossible to ignore.
Even though I've been buying MSI motherboards and PCs for years, this is surely a serious design flaw; it's a real pity, because the DC100 is a nice computer in all other aspects. I solved my problem by removing the original fan and "fitting" a huge external fan (9 cm in diameter) on the left side. It was a LONG work, because I had to cut the internal steel chassis, then the external plastic chassis, find the correct pinout and solder the small original custom connector to the new fan, remove the old fan and adapt a heatsink to take its place, route the cable and so on..
Several hours of work, but the result is completely satisfactory; the new fan is impossible to hear at maximum speed when you are 10 cm away; it's almost like having a fanless PC.
I used an Arctic F9 Pro PWM, which is 12 Volt, while the computer outputs 5 volt in that socket; it's not a problem, because in this way the fan goes at half the nominal speed (2000 rpm @ 12 volt ==> about 1000 rpm @ 5 volt), which is more than enough to keep the CPU about 10° C below the typical temperature I experienced using the old fan, while being completely silent.
At startup the DC100 outputs a message that the fan is not working (it stays for 3 seconds, then the system continues booting without a problem); that's probably because the rpm it gets from the PWM signal is way lower than that of the original fan; the rpm value returned is correct indeed, and I can monitor it in Windows.
This is the colour scheme I used to solder the old connector to the new fan:
Original fan Arctic F9 Pro PWM
Black GND Black
Yellow +5 Red
Green Sign Yellow
Blue PWM Blue
The new fan is really good; it's isolated from the computer where it is attached by using 4 rubber ties which don't propagate vibrations to the chassis. I bought it for 4,38 Euro, which would be a real bargain, if only slightly less work to fit it to the PC were needed.

Northbridge Heat Sink is running 90C. Is that too hot?

I've been having computer issues and just started watching temperatures. My Northbridge Heat Sink is running at 90C and I can't figure out if that is too high. And if it is what do I do about it? I've been inside the computer a lot lately because of graphics card and ram issues. Could that have done something? I have no idea what temperature it was running before since I've never paid attention.

I am using Temperature Monitor.
I've had several things happen recently with my computer and I can't seem to figure them all out at once.
First, my screen was freezing intermittently and had some pixeling then just finally it all went bad. After ruling out any hard drive problems I just replaced the 7300GT because I thought that was my primary issue.
Since I was already going to be opening the computer I decided to upgrade the ram as well. So I also installed new FBDIMMS - 4 x 2GB that I added to some 2 x 2GB that were added about 5 years ago.
(Side note: after the bad graphics card and before all the new hardward arrived my Airport Extreme seems to have also died on me! Haven't had time to completely troubleshoot that issue yet. I was waiting until the parts came in.)
After adding the RAM the "about this mac" showed that I had 12gb of ram running. Then the computer completely froze on me and the fan got really loud which it has never, ever sounded like that. I had to force it to shut down and then it just started up in its own. So now in "about this mac" it shows only 8gb of ram. It's not recognzing the original 2 x 2GB.
Because the of the fan getting so loud I decided to check temperatures and noticed the Northbridge Heat Sink at 90c and just wondered about it.
I'm just overwhelmed with so many issues. This computer has been great and I've never had such a rash of problems like this. It's getting over my head! And I've bothered my friends' husband enough already with all of this!

Heat sink

hello all and merry xmas to all, I have a quick question, it doesnt really pertain to this section, so let me apolagize but my I just bought a 754 motherboard to replace my old socket A one that fried. I also got a 754 pin sempron but with out the heatsink so I was wondering can I use my old heatsink from the athlon xp 2700. I know this is off top pick and I did check google but could not find the answer, sorry. Thanks for the help

Hi
What model sempron 754 pin processor? You could try the old socket A heatsink but check the temps very closely as the newer semprons do not accept the temps that a socket A processor does. A new aftermarket heat sink and fan that is rated for the sempron and motherboard would be the best way to go.
See attached link for temperature limits.

Bluetooth prevents MacBook from sleeping: related to heat sink?

I recently purchased a used MacBook core duo with a fried hard drive. I replaced the hard drive with a drive built on another machine with Snow Leopard already installed, upgraded the Ram, and everything ran well...except that the MacBook refused to sleep. I was shutting it down at night and restarting when I needed to use it. One day I started up to the blue screen -- ran disk utility off another computer, tried a PRAM reset, etc, nothing. I took it to the Apple store and they ran a diagnostic that showed a heat sink error, but the archive and install of Snow Leopard worked and restored everything.
Since then I did some troubleshooting and think the sleep issue is related to the bluetooth -- but disabling bluetooth only helped some of the time. It seems the chip heats up and then I have the sleep issue once again. I know there are threads on Apple Discussions about removing the bluetooth chip, which I could do, but I'm concerned that all these problems might somehow be related to the heat sink. Any ideas? I don't really want a logicboard failure down the road...

Any ideas?
Shut it down instead of sleeping. That's one of the dangers of buying a used machine, especially a used Mac. Why would someone want to sell their Mac unless it was broken and they didn't get the extended warranty.
My 1st generation MacBook has a similar problem. I didn't notice it until after the 3 year warranty had expired. Maybe I should sell it

G5 repaired but somewhat butchered. Can RAM slots, heat sinks be repaired?

It seems a number of G5s are sending a message of goodbye. I recently had the power supply and boot drive replaced at an authorized Apple Repair Centre but found that 7 gig of RAM was now showing as 2 (it was all still physically there). Much removing and replacing - always getting the 3 flashes at start up - incompatible RAM. Finally all replaced in original configuration, start up OK but now shows as 4 gig of RAM with a number of slots listed as empty. I suspect the RAM and slots may have got a hard time during the repair. Can the slots be replaced or are they an integral part of the motherboard?
Also, noticing rather slow, laboured operation I've seen that CPU A is showing a die temperature of 0 degrees C while B is at around 59. A has also been listed in a number of kernel panic reports. The heat sinks towards the back of both seem rather loose and wonky. Can some sort of repair be done (probably by a different repair place)?

HI-
The machine was not properly or completely repaired.
The RAM problem is typically because of failing/broken logic board.
The heatsink should not be loose, and the condition has probably fried the CPU.
If this is an Authorized Apple Repair centers work, they +owe it to you+ to make the machine right.
