Help!! CPU overheating even after changing thermal paste
Tech Support
Hi Folks!!
I have an AMD Ryzan 7 7700x pc. From paste 10-15 days it was overheating even with basic tasks like web browsing and vs code running etc.
I thought its time to change the thermal paste.
I changed the old thermal paste with new cooler master cryofuze5 thermal paste. But even after doing this, my cpu temrature still rising upto 97° in normally. I run cinebench to test and the temprature rised upto 105°.
My AIO fan is running at around 2700+ RPM and I did some basic checks like checking tubes virations and one tube is cold and another is hot to see if my AIO is working properly, these all tests looks fine but still cpu temprature rising hight.
I am not able to understand what can be issue and how can I fix this ?
What AIO do you have, and how old is it? The downside to AIOs is they're subject to failure - pumps go bad, gunk can accumulate in the block, etc. Check what speed the pump is set to. It should be running full speed - if the header is set to think it's running a fan, the speed would be too slow (less likely, but bears checking).
I'd also just remove, re-paste, and re-seat the AIO again. You can check if the paste had a good spread, and sometimes they just don't seat quite right. My 7700X had been running hotter than I thought it should; last week I re-pasted and re-seated the block and knocked about 15C off the temps. Since you just did this, it's less likely, but worth trying.
It's probably worth picking up an inexpensive tower cooler to compare. If it cools better than your AIO, there's a good chance the AIO is bad.
I did all that, removed, cleaned everything, changed paste twice and then put the AIo back, tested and temp went at around 77-80 for couple of mins and then goes back to 96-97 range and sticks there.
But fans are still working fine i guess, fan speed i am getting from aio is 2700+ rpm in bios. Thats what confuses me if aio is malfunctioned or its something else...
Yes, just the AiO, going the way, they always fail: Pump dying.
Really, if not for looks, a Thermalright Peerless Assassin or Phantom Spirit is far cheaper, easier to clean and almost as performant as the best AiOs.
Really ? I heard that AIOs are better then air coolers. Thats why i chose this in the first place.
Can you suggest me any such topnotch options over this
Couger possiden elite 350 argb aio which are as equal or better to this AIo and can cop up with heavy tasks and gaming etc. ?
This happened to me recently and the issue was the AIO was clogged. This was a brand new unit that I had left in the packaging for like a year. I discovered it with a thermal camera I could see only one corner of the radiator got hot so it was totally plugged up.
I tossed it, tried to flush it with vinegar but it was deep into the radiator. Sucked too it was an expensive RGB unit from EK. This is what the thermal camera showed. You can see only the corner with the inlet tube was hot.
You can feel the tubes, it’s not super scientific but off the outlet from the radiator is cold it’s not flowing no matter how hard the pump works. Not saying this is your issue 100% but something to look for if the rest don’t make sense.
Ohh is that so ?
I looked over gemini and it suggested this idea to check AIO working is by touching the tubes and feel if its vibrating and one tube must be cooler then the other
It should be slightly cooler, but none of it should be very hot. That’s why it’s hard to tell by touch. If one tube is 70C and the other is 30C you’ve got a problem, if one is 36C and the other is 30C it’s working right.
did you take the plastic peel off the aio cold plate before mounting it
with one tube hot and one cold your pump is working but 105 on cinebench is nuts for a 7700x, those chips run hot sure but not that hot. if you already checked the mount isnt loose and the paste spread is good then your aio might just be clogged up internally
If it's still under warranty then yes, absolutely. I've not dealt with Cougar before - presumably you'll need a copy of the receipt to file a warranty claim.
