Hello,
Specs:
Intel i9-9900k
240mm liquid AIO
ASRock z390 MB
Asus Turbo RTX 2080
64gb ram
Good airflow, 7 120mm fans.
First post here so forgive me if I say something that's incorrect or silly. I'll be as detailed as possible to prevent us having to go over the simple stuff.
I've got a strange issue I cannot seem to fix and I cannot understand what is causing it. Would love some insight and help.
Problem: At idle my CPU sits at around 30-40C. Under load (gaming) the CPU temps almost instantly spike to 100 plus degrees C and it will keep climbing. This problem only just started. It happened months ago but I re-applied thermal paste and gently shook the AIO up. My thoughts were that there was an air bubble in the line or something. The problem went away, or at least seemed to, until today. I regularly monitor all my temps. Open HW Monitor is always open on my 2nd monitor.
Solutions/Diagnostics I've tried with no luck:
-I've checked the pump rpm, its working according to Open HW monitor. I even unplugged the pump from its header on the mobo to make sure it powered down. The rpm went instantly to 0 and temps climbed at idle. The header the pump is on is showing 2160rpm and it fluctuates moderately around there.
-I've reapplied fresh thermal paste, today in fact. I'm using Kryonaut Thermal paste. The new paste lowered the idle temps a bit but it still skyrockets under load. Minecraft see 100+ Celsius, that's not right lol.
-I've tried changing the fan speeds and pump speeds. Unfortunately my setup does not allow for fan speed adjustment, it's a prebuilt and the fans and pump are using 3 pin connectors, not the 4 pin ones (if that makes sense).
-I've tried adjusting fan speeds and such in the bios with no luck or change. All set to "Full speed".
-I've tried changing the CHA_FAN1 settings in Bios with no changes.
-I've tried adjusting the power plan, nothing but lower temps at idle on the energy saver.
-I've made sure the pump is properly seated, it is.
-I've run stress tests and get the same results. Unsafe and high temps.
-I've tried running games at max/lowest settings to reduce cpu load with no luck.
-I've tried gaming with the case open, no change. I don't think this is an airflow issue as the pc ran great for years.
-I keep the PC dust free and often use my pc blower vacuum on it to make sure its nice and neat.
-I've made sure the ambient temps in the room are low.
-The PC is not on carpet and has good airflow below it and around it.
-I've tried multiple programs to make sure I wasn't giving false temp readings, all the same high temps. The pc has actually shut down due to overheating so I believe the sensor to be accurate.
The pc has worked fine for years until recently this just started out of nowhere. I used to get excellent temps under load but one day it just started doing this and I've not been able to figure this out. I've searched tons of forums and tried anything I could. Nothing seems to work.
I'm leaning towards a bad AIO or something within that system. Can air in the lines or radiator cause this problem? Is the cpu going out? Can I add voltage to the pump or rad fans to increase its performance?
I bought the pc in March of 2019 and have not had any issues since. I'll be happy to share any more info needed. I'm no pro but can do most of the basic technical stuff. I've not done anything to the pc as far as overclocking or voltages go. Pretty much been running it as it came from the supplier with no issues until recently. It is no longer under warranty either.
Any help appreciated. Thanks
