Temperature problem with processor

[-TAKUMI-]

Hello!

I've recently had some problems with my processor. 

 

The problems started after i chose to adjust my case fans after learning about optimal exhaust/intake positions. When i did this i took out my aio to get a better reach for the cables, adn then replaced it. After this my temperatures have been really high. 

 

I could run games that arent processor heavy, such as Overwatch, with a stable cpu temp of 40 degrees, but i cant even load up the game without the cpu going up to the 80 degree mark now. I have to done something wrong. 

 

One thing that im aware of that i couldve done differently is that i didnt remove the previous thermal paste with alcohol when i removed the aio, but simply wiped it off with a cloth. But i dont think there would be such a big difference in temperature if had used the alcohol, but maybe im wrong. 

 

I think the problem lies within the cooling of the processor, because i have a rather stable idle temperature at 35 degrees, but as soon it gets put under heavy load the temperature sky rockets. I dont think the problem comes from any sort of weird thermal paste application, since i redid it 3 times without any differing results. 

 

As i said, the temperatuers were normal until i chose to change stuff in the pc case.

 

Im not that intelligent when it comes to fixing with computers, so any help would be appreciated!

Rtx 2070

Just to clarify, you did replace the thermal paste after wiping off the stuff on the AIO, right? I would check the mounting pressure to make sure it's making good contact with the IHS.

I did replace it with new thermal paste, and i fastened the pump screws pretty tight.

Using alcohol to clean the thermal paste off the cpu's IHS and the AIO's water block should be fine, as long as you've cleaned it off thoroughly. 

 

How much thermal paste are you using in your reapplication? When you pulled it off to reapply it again, were there any spots that seemed to be lacking thermal paste? Are you cross tightening your AIO's mounting screws, or just going around clockwise or counterclockwise? You'll want to use a slightly larger than pea size dot of thermal paste placed in the middle of the IHS, as a rule of thumb. And, when tightening the water block of your AIO, you'll want to use a cross tightening pattern as to distribute pressure evenly. Also, make sure the the cloth you're using with the alcohol isn't leaving fibers on the contact surfaces.

 

If you've confirmed your thermal paste application is good and your mounting pressure is good, make sure you have your pump plugging in to the proper header on your motherboard, and that your radiator fans are plugged in properly. Also, of course, confirm both are working properly.

Thanks for the step-by-step guide. I actually did notice that some parts werewnt covered by the thermal paste when i re-did it last time, so i might redo it one more time and search up a guide on how to distribute pressure evenly on youtube so i do it properly!

Update on the situation:

 

I redid the thermal paste and cleaned it with some alcohol, and i actually did see a difference in tempI still have a problem with my processor spiking when opening applications, i can hit temperatures of 80 when opening a game for example, but maybe thats normal.And the cpu is still noticeably hotter than before i chose to fix with my fans and stuff. All in all im probably going to leave my pc in for a check at my local pc shop because i dont want to screw things up further. Thank you all for helping my out along the way!

Temps spiking up when starting an application is normal. It takes more time for fans to ramp up in response. 

What rpm is the pump and fans running at?

[thrasher_565]

you no when you got a good mount when all the cores are close to each other...

 

althow some chip are not placed in the middle of the cpu so... could get interesting.

 

and some cores get used more then others for w/e reason. i think the closest core to w/e its controlling is the fastest and i guess speed is based on pc trace distance. some make all them the same length. there were talks of ram being too far away from the cpu for more performance but that's way out of what i know...

the pump is running at about 1000 rpm and fans 500 rpm. Reading further into the manual of the aio, it seems like the radiator does a better job functioning as intake than exhaust (which is the thing im doing now). Is that the problem, because the temperatur problem seemed to arise when i switched the radiator to exhale? You do push hot air through the aio. Would the placement make that much of a difference?

The pump goes up to 2850rpm. 1000rpm is very low. What header is the pump plugged into? Have you tried running it at 100%?

The mounting position of the rad and the direction of the fans can affect cooling. Top exhaust as shown in your photo is fine.

I turned up the rpm on the radiator to no success, there were barely a difference. I also checked the connection on the manual and everything seemed good. But after all of this i still have temperature issues, even though it seems like ive checked everything. Im going to try and switch the radiator to intake as to see if it makes a difference.

Using the rad as intake should cool the cpu better. Did you tried reseating the cooling block? Make sure to tighten gradually in an X-pattern instead of one side before the other.

I did try it, yes, to no different result. Im probably going to try it one last time when i eventually have time to move my fans. Ill give an update on saturday!

Update:

I did replace the thermal paste and changed the direction of the fans, and also put the radiator as intake. This has however not made a big difference, and i still have unreasonably high temperatures when gaming. I even made sure to apply the thermal paste real good, i even bought some isprpoyl alcohol to clean of the old one after applying the new paste. I might have to send my pc to a proffessional, because it seems like we have gone through all of the possible reasons for the heat.

What's the core voltage at under load? Are you running at stock settings? 

[-TAKUMI-]

Sorry for the super late answer. The core voltage is at default, its around 1.25v, but it does jump around a lot (maybe thats normal? it fluctuates between 0.7v to 1.27v)

It's normal for the voltage to drop to reduce power draw when the system isn't under load. 1.27 isn't low but fairly normal for default settings. Is 1.27v the peak with the system under load?

How was the thermal paste spread?

The highest i've seen it reach was 1.29v, but it usually stays under 1.27v. I have no idea how the thermal paste application went, but since i used the exact same technique ive used before, which went pretty good, im guessing it went well. I havent seen any difference in performance however.

[thrasher_565]

i no there was some bad hot cpus and i thought it was the i7-9700k? or some were around there? were people ad to delid it to get temps down. i could be wrong thow

That's a bit higher than necessary for stock speeds but not abnormal. 

80c is fine for load temps especially if fan speeds are low. Are temps getting much higher?

Oh alright. No 80c is the absolute maximum. That feels pretty good actually to hear that

Where are you getting that? Tjunction is 100c. https://www.intel.com/content/www/us/en/products/sku/186604/intel-core-i79700k-processor-12m-cache-up-to-4-90-ghz/specifications.html

sorry, i was trying to say that it doesnt reach a temperature above 80c. Ive fiddled with fan settings and putting the fan speed as a percentage of the processor temp has decreased the heat a bit
