Fan replacements/upgrade for MDD Power Mag G4-suggestions please!

First, I apologize for again bringing up what has been a frequently discussed topic. (ad nauseum?) I tried to do some homework first but I'd like a little help if anyone has some recent experience.
I am looking to change out the large main CPU heat sink fan and possibly the two power supply unit fans in my pair of MDD Power Mac G4s. The specs are Dual 1.25ghz (fw400) MDD G4. One has a 400watt actel PSU and another has a samsung 360watt PSU. Both large CPU case fans seem to be the original delta models installed by apple. Though essentially identical in specs, The 400 watt machine has the thick aluminum finned heat sink and the 360 watt machine has the aluminum heat sink with the thin sheets. The 400 watt machine is definitely louder, but I'm not using either of them for critical audio work, so its just a preference thing on having them run a bit quieter.
Both G4s are pretty loud. The noise bothers me a little, but what I really want to do is to replace what must be now pretty old delta fans with newer, quieter fans that will help extend the life of these 2nd hand computers that I plan to use for a number of years.
I scoured the web and read many articles about MDD mods and fan replacements, but many of the articles date back to 2003 and most of the fans that people have used seem to be no longer produced or available (such as the panaflow model referenced on xlr8yourmac.com I ran into many dead links! Maybe that's because there are better fan options now?
If anyone out there has replaced or upgraded their fans in a MDD recently, could you please reply and let me know...
Where you got them
What size and model number(s) for the fans
Whether you noticed any improvement in noise/cooling
I saw a recent post about replacing fans on an AGP Power Mac...
http://discussions.apple.com/message.jspa?messageID=11628216#11628216
Would these fans be the same? I'm guessing that the MDD wind tunnel might need more cooling than a G4 (AGP) right? SOme places mentioned that the main fans were 119x119x25, while others mentioned that hey were 120x120x25. Is 1mm going to make a difference? I'd prefer not to have to dremel them if I don't need to!
Lastly, if you have a direct link to a reasonably priced fan that you'd recommend, I'd appreciate it greatly!
Thanks for any help!

Thanks Japamac!
Thanks for your replies! Those look very good! So many to choose...
Exactly the info I was looking for. I was checking out the panaflow (I was a bit overwhelmed by the number of choices on the 'Performance-pcs' website... if you were buying, which one of those 34 would you get? Assuming a budget of 20 bucks per 120mm fan...)
But a followup question on the Panaflo model you linked to. In the many web articles I read I recall that one being well regarded. ,IF I buy that one, I have a few choices on tail options...
3 pin
4 pin
4 pin male molex with separate 3 pin rpm connector
Am I correct that if I opt for the last option I can get the fan to run at a medium rpm all the time and have it be less likely to ramp up under heavy loads?
Lastly, will this possibly be a problem I might have, simiar to what was noted by a xlr8yourmac fan modder -->
http://www.xlr8yourmac.com/systems/g4mirrored_drive_doors/noise_reduction/g4_ddr_noisereduction.html
"(Updated comments added 7/9/2009)
I have an important update to that G4 fan mod note I gave you.
I noticed that the 120mm fan wasn't pushing as much air as I thought it should, and I realized it was because the 2-pin fan connector on the motherboard wasn't providing enough power. +(3 pin connectors typically are for adjustable/variable speeds. But if it's a constant speed fan then maybe the 2 pin wiring was using only 5V vs 12V? (higher voltage = higher rpm fan speed typically)-Mike)+ I put the 3-pin connector back on and used a 3 to 4 pin Molex adapter adapter to connect it to the 4-pin hard drive power cables -- voila! Lots more air. So... Following the directions in the older article exactly may NOT work depending on the fan you get. Also, using a 3 to 4 pin adapter is much easier than modifying the connector from 3 to 2 pins as indicated in the article."
This was confusing because I thought that there was just a 3 wire lead to connect or splice, with the yellow wire probably just not being used.
Your thoughts?

Replacement/Upgrade for High End T60p

Anyone have any advice for a replacement or upgrade to my T60p? My T60p, T7600 15.4" Wide UXGA is getting a little long in the tooth. I have not kept up with the Lenovo line, and don't know where to start.
T60p 8743-CTO, 8742-W7W, 8741-C4U
All T7600, 3GB, 15.4" UXGA, XP Pro SP3

If money is no object the x300's with a docking base is key since you're sacrificing the unltrabay in an X system.
OR if you mean your T60 is old and beaten but you still love it, you can buy a certified preowned model from IBM and I think Lenovo but IBM sells returned leased systems typically spent the last three years inside a company maintained by an IT group since ThinkPad's premium price is recognized by affluent and staffed companies qualified to maintain them.
Their warranties are just as good as a new one and their tech support calls are answered by the same group in Atlanta that handles the newest W series.
ORRRRRR, if you just want more power you can spend less than $500 and upgrade the HDD into an SSD, but do so only if you don't have any thermal issues with your T60 since SSD's execute instructions literally 10x faster than a spindle and will throttle your CPU to 100% like an athlete.
The CPU doesn't slug, but it just won't be challenged so briskly and it runs like an athlete at peak pulse, Thinkpads are terribly accepting of SSD's and become mini monsters regardless of the age and T60's are very SSD friendly.
The OCZ drives are better bang for your buck, the Intel's have reputation behind them, we use both and can't tell the difference and an OCZ isn't a bad choice at all.
TIP;'''' Avoid buying a super drive like an Intel X25E because the T60 technically has an encumbered SATA controller and it won't take advantage of an X25M's splazing speed ! Even the encumbered controller is hard to notice but it has the community in an uproar since it takes two seconds to boot than the x200 and that means your T60 will take a whole 28 seconds to cold start instead of 26 seconds.....poor you.

What is the Best & Max Upgrade for Used Power Mac G5

Hi All,
I need your help on purchasing an old Second hand Power Mac G5, which will coast me nearly 1900$ with 20" Cinema Display? is this price is OK for the below Spec.:
Processor: 2.0Ghz Dual Core (1MB Cache for single core)
RAM: 512 MB, DDR SDRAM PCI 533.
Graphic Card: Nvidia 6600 128
Hard Disk: 160GB
And Super Drive for the DVD Rom.
As you see its have an old Graphic Card and Small amount of RAM so what is the best amount I can Add on RAM and Best Graphic Card to get the perfect performance?
And What is the max size of the hard drive supported by the machine is it 2TB or less?
And last not least can I install the new OSX (Leopard) on the machine and is there any difference between MAC Pro G5 and Power Mac G5?
Looking forward for the answers and hopefully as soon as possible because I afraid somebody else will gonna by it, Thanks for the support and Good Bye.
Thanks & Regards,

Hi! It all depends on your use. If the machine is to be used for serious work such as video editing and Photoshop use then the more power you have usually means more productivity. On the other hand if you are just surfing the net and using word applications like Microsoft Office then nearly any machine is suitable. The early G5's could use 8 gigs of ram and the newer ones 16. Look HERE for late model specs and look HERE for slightly older models. For most people the fastest iMac is a hard machine to beat but there are tradeoffs with an all in one machine. If one component fails it's hard to repair but with a tower design such as a G5 or MacPro the components are easily more replaced. Also expandability with a tower is easier. You can multiple hard drives to a tower that you can't with an all-in-one machine. The new Macpros start at 2799 as per APPLE's SITE while the fastest iMac is 2199 as per APPLE's Site. I'm not a video card expert nor a raid expert so I'll leave those questions to others. Tom

Can i get a replacement/upgrade for my powerbook?

hi,
my powerbook has gone in for repeat repairs lately, none of which fix the problem.
what are apple's procedures for deciding that the powerbook is just NOT going to be fixed. in other words, when will they just give me a new one?
mac geniuses have replaced hard drive twice, and logic board, and reinstalled OS multiple times, and it still hangs as soon as i get it home.
i'm about to go back to the store, and i want to know what kind of case i have for asking for a new machine. how many times are they going to try to make the same repairs? my warranty runs out in one month, and i need this problem solved before that time comes.

Welcome to Apple Discussions, nay nay.
My understanding is that after three major hardware failures within 12 months you can negotiate for a replacement or refund (depending on the circumstances).
Since you have already had two replacement drives and a logic board, then I think you have a pretty good argument for a replacement. However, they may not always be pro-active in letting you have a replacement so you may have to be prepared to argue your case. If necessary you may have to negotiate directly with the store manager rather than just a Genius.

IMac extremely slow after upgrading to OS Lion...suggestions please..

We recently upgraded our iMac to OS Lion from Snow Leopard and it seems like everything now takes twice as long to start. Opening applications, opening documents, switching to another user name, pretty much everything takes forever. I love the operating system, but feel like I am using a 10 year old computer. If anyone here has suggestions on how to speed things up, I would greatly appreciate it.
I have tried logging out all other users to free up some of the memory and that really doesn't help.
I love my Mac, please help....

If it is a new installation, spotlight can take forever to do the first indexing. I put my Sleep option in Power preferences to "never" (On mains power that is) and leave the computer lid open / on all night.
There are also other things going on, like, software updates,(both from Apple and third party), maintenance scripts (that run on schedule at night), Backup, iDisk and iCloud syncs (the first uploads can be large), etc.
Once the initial cludge is cleared things get much better. But get that RAM upgrade. Crucial delivered mine within 24 hours of ordering
You'll need a very small screwdriver!

Power Mac G4 MDD power supply unit/RAM

Hello,
I just bought a used Power Mac G4 (Mirrored Drive Doors) at a garage sale for $20. The owner said it works, but he took out the RAM, power supply unit and hard drive.
I would like to place an order for the RAM and power supply unit but I am not sure how I differentiate which power supply unit to purchase. When I try to look it up all I find it is that it had gods gift to worst ever power supply unit in the history of power supply units. It was the loudest most obnoxious fan set up or something of the sort.
Well bottom line I need to get a few replacement parts for the old G4 desktop and was hoping that some experienced mac hardware person could point me in the right direction. I am comfortable replacing parts I am just not certain what I need to purchase to install.
Does anybody know of any good 3rd party hardware that they could suggest for a replacement part?
Power Mac G4
Designed by Apple in California
Model No.: M8570 EMC No.:1914
Thank you very much :]
(I am pretty sure I posted this in the right subcategory, sorry if I did not.)
None of these model numbers match, but it everything I research says it was from this generation of G4’s. How can I 100% tell which one is the model I have?

I just finished rebuilding my MDD (FW800). As for finding specific parts for your machine, be sure you have the model number, or are able to differentiate between the models. That being said, most of the case parts are interchangeable. Problems can occur when swapping processors and failing to use the proper heat sink for that processor.
The best place (price wise versus availability) that I've found for MDD power supplies is on eBay. However, be aware that you will probably be getting it used. So either ask the seller if they will guarantee it for a specified period of time, or buy it from a seller that offers a guarantee (normally 30 days). If you get one that lasts for 30 days without any problems you've probably got a good one. Price is normally around $140 + shipping.
Another avenue is to try shopping the web (Google) for what you need. There are a number of great websites that carry what you may need, or maybe are looking for. Some of those to checkout are:
www.applecomponents.com
www.otherworldcomputing.com
xlr8yourmac.com
www.lowendmac.com
Additionally there are a number of case and power supply mods that can be done to quiet down the MDD. Apple doesn't necessarily endorse these mods, as they deal with changing power supply cooling fans, and/or the processor/case cooling fans. However, if your MDD is out of warranty, you practice safe electrical/static work practices as you're working, and you're willing to accept any negative consequences should those mods either not work properly or they happen to result in damage to other components, then do what you feel is appropriate.
As for telling exactly which model you have, and how it was originally configured when it shipped from Apple, research the serial number through this Apple website. Another way is to check the model number of the motherboard. This is located near the PCI slots, by the modem connection. It will have a number something like 820-1453-A, or 820-1500-A. Cross referencing these through Google can help tell which motherboard you have. As for the processor, you'll need to carefully remove the heartsink (5 screws) and look at the chip(s) itself. If there are two chips it's a dual processor, and if only one it's a single (Duh!). Then locate the small white sticker that's stuck to the processor card for the processor's info. It should tell you what you need to know about it. You can also look at the info inscribed on the face of each processor chip.
Important Note: Be very careful, and wear a grounding wristband at all times when when working on the inside, or handling any computer components. This is particularly true when handling the processor card, and here's why. Any static shock from you to the motherboard or to the processor could severely damage or destroy that component.
Here's another link to way of quieting the MDD.

Anyway, I hope these help you find what you need. Be careful!!

When using Craigslist I keep getting this error: Warning! Domain mapping upgrade for this domain not found. Nothing I do works to fix this.

When I use Craigslist, my personal list of things being sold, and I try and renew my listings, I periodically get this: "Warning! Domain mapping upgrade for this domain not found. Please log in and go to the Domains Upgrades page of your blog to use this domain." Usually rebooting my computer makes it go away for a short time, but today that isn't working and following the commands on the warning doesn't work either...is this truly a firefox issue?

Replacement Printer for HP 2100TN

I have an obsolete (according to HP) networked printer which has ceased to function. No one can tell me why it has stopped. It was designed to work with OS9, and I am now using OS10.4.8, and HP will not support it, or even answer questions. I get the following error message:
"Unable to connect (retry in 30 seconds). Cannot allocate memory."
Siince I cannot figure out why it won't work, and need a printer, I would like to replace it. Can anyone recommend a home network printer as a replacement? Color is not necessary, but do wish to stay with a Laser printer.

MDD power supply and fan upgrade kit question.

Hello, Its been a few years since I posted anything here and I'm getting ready to (possibly) trade in my mirror drive door 1GHZ dual processor machine on one of the current imac-s.
I'm not real hopeful that putting much work into my current machine is worth it. Here's why:
1) crazy levels of noise - I wear woodworking hearing protectors when I surf the web. Listening to music on itunes is fine so long as you like a background of low level blow dryer noise!
2) I'm still running OSX version 10.2.8, I have been too cheap to buy the latest OS. I'm tempted to go out and spend the $119 on 10.5 but I only have the original 256mb of ram installed and since the min requirement of ram is 512, I know I'll need to spend an extra ~50$ on a 512mb PC2700 ram chip. My price tag to do a minimal update is rising...
3) I would love to neutralize the noise and install the Apple provided MDD power supply and fan retrofit kit that they sent me at no charge several years ago while I was still under warranty. But I never did because the tech at my local (Dayton Ohio) reseller told me that the kit only addressed high noise levels when rebooting in OS9. So I never bothered. Looking on ebay, I see where power supplies for G4's could fetch 75 or 100$ or so.
In summary, here are my questions.
1) Has anything come along recently to tame MDD G4 fan noise that is easy to install, cost-effective and most of all, something that actually works to decrease the noise?
2) To get the quietest, quickest performance with the current OS 10.5 should I cut my losses now and trade (or sell on ebay) my MDD, sell the new power supply and just purchase a new machine with the OS already installed?
Thanks a bunch in advance for any assistance...
from Bill.

Bill,
Carl has some pretty good points that I'd agree with - trying the replacement PSU and fans should quiet it down somewhat and replacing the stock main fan with a newer, quieter unit will also help. But I'm going to disagree with him on running Leopard on the G4's with a few reservations.
As you might notice from my profile, I'm running Leopard on my dual-867 MDD and find the performance acceptable; perhaps a little slower than Tiger in some respects but it does run well enough within the limitations of the G4's capabilities. The reservation I have about recommending Leopard on a G4 is the graphics card - without Core Image support (which you won't have unless you upgrade the video card) Leopard is going to tax the CPU more and may bog down in some tasks like Quick Look and Cover Flow.
In the end, whether to continue upgrading the G4 is a matter of use and economics. Tiger would be a fine upgrade with minimal cost and squeeze a few more years out of your G4 if you're not requiring software that needs an Intel CPU (like certain iLife '08 apps).
