High CPU temperatures on new computer

The temperatures on my CPU (i7 6700k) eventually settle on just over 20 °C right after start-up. However, while watching YouTube videos and having other non-demanding programs open, the temperatures sometimes spike to just over 70 °C. I'm guessing this isn't normal. Furthermore, while running simulations the CPU temperatures go up to 95-100 °C.

I got the computer at the end of November last year, and I experienced some blue screens now and then, and during spring they were relatively frequent, but they mostly happened while I was running simulations (World of Warcraft was also on in the background, and I tended to tab over to it while waiting for the simulations to finish).

Did I mess up the thermal paste perhaps? Normally, a new computer doesn't get blue screens like that. I haven't had them in several months now, but I haven't been running simulations for equally long, either.

Your CPU is thermal throtteling, this is why you are getting blue screens. The CPU is getting to hot and it shuts itself down to prevent damage to the chip. I would not use the PC until you get the cooling fixed.

Without knowing what type of cooler you have, I would say that it is not installed properly or damaged. I would reinstall the cooler and see what the temps look like. Make sure you have the cooler seated on the IHS and thermal past is applied properly. My guess without looking at anything is your CPU cooler is not seated on the IHS.

If it is overclocked, then clear the CMOS to restore to factory defaults. Your voltage may be too high, but still your temps show your cooling is not performing as it should.

I have not done any overclocking. The cooler I'm using is be quiet! Dark Rock 3.

I figured I'd have to reinstall the CPU cooler, or at least the thermal paste, but I wanted to see if there was anything else I could do first.



The IHS is the little platform on which the thermal paste is applied, right? If so, I didn't realise it was even possible for the CPU cooler not to be seated on it. If it's screwed into the correct mounting holes, then one would think it would be seated correctly.

I did not know what type of cooler you had, some of the coolers to not use screws instead the use pegs and they are not so easy. Also, your screws may have come loose or the bracket was not installed properly therefore the heat sink does not have good contact with the CPU.

I know installing a cooler is a pain, but if you are not overclocking and have not messed with the bios, then there is a 90% chance (maybe 99%) that your CPU cooler is not installed properly, thermal paste is not installed properly, or the CPU cooler is malfunctioning (in your case the fan is not working).

The fan is spinning without issue, so I'm guessing there isn't anything wrong with it. I suspect the thermal paste may have been messed up while installing everything. Mounting the CPU cooler was a pain, as I had to screw it in from the back, but the motherboard had to have its front facing up because gravity.

Is it very important what kind of cleaning solution I use when wiping off the paste? I don't think I have an alcohol solution around, but I have some general cleaning solutions, including one that my mother was given by someone in order to clean a copy machine at work.

I use isopropyl alcohol. As it will evaporate very quickly. You want something that will evaporate very quickly. I have never used anything else, so I dont know. Unless the thermal paste is burned and caked on (which it may be), then you may be able to get it up with just a tissue.

So, I have an update. It's not a very happy one, unfortunately. Essentially, I'm not even a bloody idiot. I'm worse than that. I'll just let the picture tell the tale:

I don't really know what to say. It's unfathomable how something like this could have happened, how someone like me could be subjected to such a farce.

Needless to say, no more problems. I tried running a simulation again, and the temperatures hardly even touched 55 °C.

We have all had those moments. Just be happy that you have figured it out. I knew there had to be something wrong with the cooler.

Cheers for all the comments everyone. Now I can finally move on to overclocking the CPU and take advantage of its full power.


Indeed! I agree.



Very amusing read. It does make me feel better, so thanks.
