How how is too hot for Core i7 3770?

For my Z77A-GD65 system build. Using HWMonitor to observe temps across each core an on the package.
At what point is "hot", "too hot".
With no overclocking, with my stock intel fan, I'm at 40C at idle. When Prime95 or any stress app is run, it gets into the 75-80C range. When does it get to be "too hot" where I should consider better cooling and heatsink solutions?

By current Intel documentation calculations, it is 89C for a 3rd gen 77W CPU. Normally, I don't give answers that can be found by doing some self research, but currently as listed, TjMax is 105C. For years, heat has been an enemy to pc components, but in all fairness, the production quality and temperature tolerance has greatly improved beginning with 5 series chipsets, recent memory chips, and VGA's. Along with heat, voltages applied can also have a dramatic impact on longevity. That is why it is important to 'know the limits'! Components are built with limits by the manufacturer, unless proven otherwise and documented, a CPU at 70C will not suffer degradation any less than a CPU running at 88C (3rd Gen CPU). If the temperatures and voltages are within the manufacturers specifications, there is no need to fret about them.
Getting rid of that factory TIM on that stock CPU cooler and using a proper amount of AS5 or MX-2 might reduce that temperature by up to 10C.

How How is too hot for Macbook

Hello,
I have a 2008 Macbook Aluminum and I use it everyday for school work. It was passed down to me due to an overheating issue. After repairing it myself I discovered that the fan was not working. I replaced the fan and the computer has been running good since. However I still notice the temperature on the CPU getting hot. I have many computers but all are PC's which manage to keep their temps down. My mac runs normal idle at 120F. During some operations such as minecraft it gets up to 180F which is excessive, I have downloaded SMC fan control and start to compensate fan speed when I notice that the CPU Temp is getting high. I recently got a software from the AppStore to make digital copies of movies. It works good but got to 185F I cranked the fan up to 6000RPM and it seemed to cool to 170F which was still hot. I have made some upgrades to the computer it is running Yosemite (Before updating it still got hot), it has a Intel DualCore, with 6GB of RAM. I just want to get the opinion of people on this forum. Thanks!

Hi wanster,
If your macbook still under warranty like you said (9 months), just bring back to apple, for battery shouldn't generate heat. Are you sure the heat was from battery insteadof the macbook processor?
Try to run battery updater 1.2 first and see if that will fixed it.
If the battery become hot, something internal might got short, and I suggest to take it off to prevent more damage to battery, macbook and yourself.
Good Luck.

How Hot Is Too Hot For Late 2008 Macbook Unibody?

I'm still in the process of adjusting to life in the world of Macs and I was wondering just how hot is too hot for the CPU to be running at with the Unibody 13 inch Macbook?

The sensors are set to put the computer in thermal shutdown at 212F to prevent catastrophic damage.

How "hot" is too hot for new MBP?

What would you consider too hot for my new 2.8Ghtz MBP?
Istat shows temps around 150-165f with fans running 2001rpm most of the time.
It feels very warm to the touch underneath.
Thanks

something is wrong with the new MBPs cooling system!

How hot is too hot for a laptop

My new dv7t Quad edition laptop was recently delivered and I am wondering about the heat issue that others have mentioned. The computer does not get too hot to touch but there is warm air coming out of the vent almost all the time. When I have several programs running the fan seems to come on fairly often, which I understand is what it should do.
How do you tell if the laptop is too hot? Is some heat inevitable for an i7 processor?
I really like all the features of the computer but I want to make sure it is ok before the 21 day return period has gone by.
Thanks.
Jack
This question was solved.
View Solution.

To my knowledge, Maximum allowed temperature for Core i7 is 100°C and recommended is 80°C. If it heats up more, the CPU will enable thermal throttling, i.e. the Vcore and clock frequency multiplier will be forced down to 12x. This feature protects the processor die against dangerous overheating.
The warm air flow from vents is by design of the notebook. That is the specific reason for having the vents.
When ever the load on the system increases, the temperature increases. When the temperature inside the system increases, the speed of the fan increases.

How hot is too hot for an eMac

Hello
Today was very hot. It is now just after 6.00 pm and it is still 37 degrees celsius. Does an eMac (ATI Graphics) have a variable fan speed, it seems to be really blowing hard, or maybe it is just the sweat trickling down my face that is imagining it.
I know my iBook's fan revs up to a higher speed when it gets too hot.
What is the maximum recommended operating tempreture for my eMac.
I can't find it in the manual.
Thank you
regards roam

Hi, roam. You may just need to accept that your eMac's life is likely to be shorter than some others because of the adverse conditions it has to endure. If you do opt to buy a fan to help cool it, be sure to position the fan to blow air into the eMac's air intake vents, wherever they are, and NOT to blow air at the eMac's outlet vents, wherever those are.
I don't know whether it's dusty in your part of Oz, but you should be aware that dust inside the case dramatically impairs cooling, and that moving more air through the case will probably increase the rate of dust accumulation in there. I'm not familiar with eMac take-apart procedures, but if there's a way you can open things up periodically to blow the dust out, that would be a good idea.

How Hot is Too Hot for the Wireless Module

I have noticed my Wireless Module is running from 127 deg F to 131 deg F and wonder what is
too hot? At what temp should I become concerned?

131 F is not very hot, you know.
If I knew that I would not have posted the question. I have heard the iMac will
shut down if it gets too hot; however, I have no idea what is too hot.
When I ran the migration assistant to transfer files for the G4 to this iMac, one
of the hard drives got too hot and the migration assistant gave me a waring that the
transfer was stopped waiting for a drive to cool down. After a few minutes, it
started up again. That was very scary!

Is this too hot for my MacBook Pro?

Hey guys,
I run Bootcamp on my Mac (OS X during university, Windows 7 for games on the holidays haha) but I have noticed my computer gets really hot.
I have a 2011 MacBook Pro 15' 2.2 i7.
At the most (using coretemp) my Macs CPU appears to get as high as 100C. I know the max for my chip is 100C, so is this a problem?
It usually runs a little lower (87-97C) but I still worry there is the possibility of damage. It should be noted that at these temperatures it sounds like a jet engine is inside the case (obviously the fans).
If this is a danger how long is too long for the computer to be at these temperatures?
Kindest Regards.
Tyler

At that temperature for a sustained period of time over time will lead to your thermal paste on the CPU to fail. Actually, alot of the thermal paste sitting on the board will fail eventually but at high temps for sustained periods of time can't be great. And if you've ever seen iFixit's breakdown of the macbook pro, there are gobs and gobs of thermal paste all over the dang thing.... I say use away and make sure you get apple care !! hehe because if any of the problems you get are related to hardware it can always be fixed.... or swapped
But 100 C is not that hot for a CPU or GPU... in fact it's borderline warm. Most CPUs I have run up 140-165 and operate around that temperature... I think your safe for the most part. Just backup your stuff onto an external occasionaly, and if worse comes to worse make sure you have apple care and bring her on in.... I'm curious to hear what other's say about the operating temperatures. If you look in your manual Apple says normal operating temp is like 50 - 65 or something and they say 105 C should be your max....

127 degrees F.. too hot for new iMac ?

iStat Pro says my new iMac HD temp is 127 degrees F. Is this too hot? The top left side of the case is almost too hot to rest my hand on. The case gets progressively cooler as I run my hand down the side.

127 degrees F is not too hot at all, mine regularly gets there and comes back down. You are resting your hand on the exhaust vent so of course it's going to be hot. I have seen my machine get as hot as the high 130's with no adverse affect. It seem like the temperatures are influenced by how warm the room is and if you are doing something that is graphics intensive. Also having vents that are blocked or living in a dusty environment can influence temps. My advice would be keep your iMac well ventilated (the intake is at the bottom of the machine) and once in a while when the machine is turned off vacuum both intake and exhaust vent to pull any dust that my have accumulated.

When is it too hot for your mac pro?

I recently switched graphics cards from the x1900 ATI to their new HD 3870 because of heating issues. While the new card is not having problems my Mac did freeze when the internal temp from my SMC control read 97 degrees. At what point is hot too hot and is there some way to cool the temp besides increasing fan speed (which didnt seem to do the trick anyway)?

Is 85c too hot for ram?

Have 2x 2 gig ram modules --- without smc fan control intervention 1 runs at 85 c. Query, is this too hot and should I replace that module? In replying please advise of what temps your memory runs. thanks.

Temperature Report from XLR8yourMac has quite a bit of information
From the author of Hardware Monitor:
- Each FB-DIMM contains its own controller, called "Advanced Memory Buffer (AMB)".
Each AMB also contains its own temperature sensor. The maximum temperature of an FB-DIMM, measured by the AMB, lies in the interval between 95 and 125°C (it will vary from manufacturer to manufacturer), the typical value is 110°C. So all memory-related readings mentioned in the thread should be considered low and well within specs.
I hope this information is helpful to you. If I can be of further assistance,
don't hesitate to contact me.
Best regards,

How hot is too hot for macbook batteries?

Does anyone know how to keep a macbook battery cool? I have a macbook with dual processor that is about 9 months old. Two weeks ago, the hard drive failed and was replaced at an Apple store. I now notice that the battery gets very hot after really short use times-like just checking Mail. I'm wondering if the battery can get hot enough to fry my hard drive, and if so, what to do to prevent this happening again as I've already lost enough data (I'm a newbie and still have not figured out how to back up to my new and very large external hard drive).
Thanks.

How hot is too hot for a northbridge?

I hope this isn't a stupid question but I happened to come across a monitor which measures the temperature of various components of my computer and I was startled to see that the temperature of the northbridge in my dual core Intel ranges normally between 135 and 145 degrees F. Can that much heat be a normal occurrence? Anyone know? Should I be looking for an aftermarket active heatsink? Or am I making too much of this?
Thanks a bunch.

Thank you for this. It would appear that with my configuration, an average temp. of 140 degrees F is perfectly now. Now I can go about worrying about something else.
Thanks again!

How hot is too hot for CPU's?

Melting through the bottom of the case like a runaway nuclear reactor is obviously bad...
BUT! What temperature ranges should be be looking at for standard air cooling with a quality heatsink and fan? I am running the intel provided retail heatsink and fan atm as the much more expensive unit I bought (the SP-94) wouldnt fit in my case at all.
So! Currently at idle my CPU temp is 36c, but it is also a little cold in my house. I have seen temps as high as 55c under load. Anything I should be concerned about as I am overclocking a bit? I am running 220x16 so running my 3.2 at 3.52ghz.
Thanks!

Increasing the FSB provides for better system throughput, but just increasing the multiplier of the cpu does not, therefore, you might want to try decreasing the multiplier when you increase FSB.
The formula is pretty easy. Take the max stable CPU Mhz setting you have, 3600(=225x16), and then divide 3600 by the new FSB value you want to try. The result will be what you should set the CPU multiplier to. Doing this repeatedly will eventually give you the max stable FSB value you can run @ your stock voltages, and then you can try to tweak up your multiplier again. You might have to up both memory and CPU voltages to get past the 3600Mhz total, but only do this one step at a time. You're looking for the MINIMUM voltage increase to achieve stability.
HOWEVER, I don't recommend radical OC'ing to anyone who has only stock cooling, or who has a big heatsink on the CPU only. The whole system needs to be cooled as evenly as possible: CPU, RAM, chipset, motherboard, video card, and should be done BEFORE OC'ing. Otherwise, unless you have deep pockets, you might go broke buying a whole buttload of replacement parts.

How hot is too hot for the the CPU?

Using a widget, I've noticed that my CPU-A is running at temps at or above 200 degrees Fahrenheit at times. Despite those temps, the fan is not kicking on.
Is this normal? I don't ever recall my previous Mac getting above about 140 degrees

This is a life saver and I've always had it
if your problem still persist after resetting.
just download this !!!
