CPU Temp Well Over Safe Level

[Broadleaf]

I built my computer around 2 years ago and back then my CPU temps were probably ~10 degrees Celsius colder than they are at idle right now (40c).

After I built my computer I stopped caring about temps and pc parts and all that stuff unless there was a specific issue, but recently I looked in to finally overclocking my cpu since I was looking for more frames in a game and I noticed my temps were spiking to over 100 celcius at some points, with one core peaking to 109c At idle I'd say my temps are just "okay". Already on the higher side for idle for sure though. A little worrying but whatever. But it is not normal for my cpu to burn to 80 degrees celcius when compressing a file, or to shoot up to 109 when exiting CSGO.

I don't know why my temps are so friggin high.. I take care of my computer and though it has been a couple months since the last big interior dusting, I feel something else is happening that's influencing my temps. All my temperatures for my other internals are good to great levels

so I don't understand, that would mean it can't be the temp of my computer case right?

Keep in mind these temps are at STOCK levels. I use an H100i and so many fans jeez. My case is a Phantom 410. These are the rpm my fans have to run at right now

to achieve even these horrible temps...my computer sounds like an airplane it is very loud.

I am scared to find out what damage I might do while I'm playing games more intensive than CSGO. These temps should not even be possible with this setup is how I feel right now anyway... computer might as well be in a furnace.

BTW: My room is not too hot, it's less than 20 Celsius year round.

My first assumption is that the cooler is mounted wrong or you did not use enough thermal paste to see temps like that with a H100i and i5 4670k at stock, thats way too high. Can you hear the pump in the cooler working?

Remove your CPU fan, clean and reapply some new thermal compound.

Also, are you sure your CPU fan is working?

I can hear the pump working yes. Corsair Link tells me the pump/fans are running at well over 2000rpm, closer to 2.5k. It has been 2 years since I installed the components. I am pretty sure there was some sort of pre-applied paste that I kept with instead of adding my own. I checked online when I built it and people said it was fine to use so I trusted them. Maybe I was wrong?

Also if it means anything I think maybe the radiator fans are positioned to push air OUT of the case. Maybe the case airflow is the problem thought it doesn't get hot.. I'm just kinda at a loss. I thought everything worked fine for two years now I see 109 degrees so obviously something is wrong.

I'll try the thermal paste but I have a question about that too: As long as my temps dont spike to those dangerous levels I can safely continue to use my computer, and also will I have to clean the previous pre-applied paste off the heatsink or something like that?

Never was good at this stuff.

If you have a thin motherboard then the H100i's mounting bracket won't provide the proper clamping force of the waterblock to the CPU's heatspreader.

If the backplate is loose before you even attach the waterblock and pump assembly then you know you have a known problem.

The mounting post retainer should not be protruding above the top of the motherboard like this:

They should be like this:

To solve the problem add a #8 flat nylon spacer (available from a hardware store like Home Depot or Lowes if you live in the U.S.A.) in place of the metal washers shown in this image:

I'm so sorry to have taken time away from all of you.

Looks like we've been getting more dust than I thought.

Cleaning this would probably lower my temp down a little bit wouldn't you think? 😛 Thought so big never though to check the simplest solution. Thanks for your time and your help

Lol well there is your problem. Give that a good clean, you may want to give it a dusting more often I usually clean mine every couple months. And maybe get some fan filters on your intake fans, also make sure you have positive pressure in your case (more air being brought in than being exhausted) because that is quite a lot of dust.The cooler of your gpu is probably caked with dust too.
