What Temps Are Too High?

[Michael McChesney]

I know that CPU or GPU temperatures that reach triple digits Celsius are a problem.  But I am not sure at what temperatures I should become concerned.  I am sure that duration is a factor as well.

 

My system is running a Core i9 9900K, with a Cooler Master Hyper 212 RGB Black Edition 57.3 CFM CPU Cooler, a Gigabyte GeForce RTX 2060, and 32 GB of Ram.  My case has 2 intake fans in the front and one fan blowing out in the rear.  I am using NZXT's CAM software to monitor temps.  I am not overclocking anything at this time, though I may explore it in the future.  

 

I was using HandBrake to convert a 1.5 GB .avi file to an .mp4  using HQ 1080P 30fs, while listening to a YouTube video and playing Spider Solitaire when CAM warned me my CPU temp had reached 85 degrees C and that prolonged use at that temperature could damage my CPU.  I stopped the video and my oh so demanding game, but figured it would be OK to let HandBrake finish rendering the video.  The annoying thing is that CAM sent me about a dozen warnings during the render because the CPU temp kept fluctuating above 85 degrees and below and sent a notification each time.  As soon as the render was done the temperature fell like a stone into the 30's.

 

Is 85 degrees C a problem?  How much of a difference does it make if it was at this temperature for only 8 minutes (approximately)?  I notice my graphics card (RTX 2060) tends to run about 5 degrees warmer than my CPU when both are mostly idle (currently 38 and 33 degrees C respectively).  Is a graphics card designed to run at a higher temperature?  Or is the temperatures at which I should be concerned the same for both?  Is the CAM software a good choice for monitoring temps or would you recommend something else?

 

Thank you in advance for your advice.

85 is pretty warm for a cpu, I generally don't like it above 70. Not saying you mounted the cooler wrong, but I would try redoing it. If problem persists, I'd definitely go with that the 212 doesn't suffice for a 9900k and you should look at something heftier like a dark rock pro 4 or D15

Stressing it 100% usage? I mean that's insufficient cooling to keep its 4.7ghz boost efficiently, 85Cº is already about to start throttling in frequency.

You are running a 9900k, even with a beefy air cooler or AIO it usually hits around 80+ Celsius at load. Getting those temps on a Hyper 212 are completely normal

The 9900K is a hot and power hungry processor. It needs heavy duty cooling for good temps.

I had figured an air cooler would be sufficient if I wasn't overclocking.  Would a beefier air cooler be my best bet, or should I look into an AIO?  If I decided to look at an AIO water cooler, how would the Cooler Master MasterLiquid Lite ML240L RGB AIO CPU Liquid Cooler be as an option?  I saw that on New Egg for $75.  I am not sure what a more expensive AIO would bring, other than more elaborate RGB (which I don't care about at all).  Is there a different AIO that you would recommend?

 

Thanks for the advice.

Hey there!

I had the same processor running at stock with an 280mm all in one and it still hit 80c+ especially when I don't run my window AC.  Before you drop 70 dollars or more on a cooler, try undervolting and looking up some guides. My 9900k was hitting 1.35volts or higher with stock motherboard settings and even the VCCIO and VCCSA was at 1.3volts for some reason.  I settled on 1.22volts for the cpu at 4.7ghz and dropped the other two voltage settings to 1.10volts.  My 9900k loads around 70-75 celcius when my apartment is at its hottest. Just food for thought before you spend all that money.

I personally consider anything over 75c will running a stress test hot and like to keep it around 70c or under. Will 85c damage one? Not sure to be honest. I don't think it will last as long if you are hitting hard all the time though as one that runs 10 or 20 degrees cooler.

 

A really good air cooler should perform about the same or better than some AIO coolers, there are a few videos on youtube about it, one from Linus not that long ago. I wouldn't expect a cheap small one to though. But if you are getting name brand coolers in the 70 to 100 dollar range performance should be pretty close. IF you have good case management and air flow. I went from a cheap 40 dollar deepcool or whatever they are called air cooler to a 130 dollar corsair h100i pro aio and honestly it isn't that much better. Don't get me wrong, it is better but it didn't blow my socks off or anything.
