Thermal paste question

[Enxquity]

So, I recently got a used H100i Extreme Performance AIO and temperatures went to 100 degrees celcius under load so i thought it was broken; however, I was told this is due to the thermal paste. I have ordered Arctic MX-2 thermal paste and wanted to ask how much of a difference this would make.. I currently have some worn out old thermal paste on my cpu and im pretty sure it's dried out fully.

 

I just wanted to know what temperatures i would get with the thermal paste applied?

 

I bought the AIO cooler since I wanted to try some overclocking but i'm not sure if this would be possible.

if you didnt even repaste, that's definitely the culprit. thermal paste isn't really reusable

So this would impact it alot? Since I really wanna try get into overclocking.

yes, fresh paste should have a very large impact

How much degrees do you think the cpu would average on base clock 100% load?

I can't say because I don't know what case you're using or what airflow or fan profile, or if your room is a hot room or something

 

what I can say is that it won't thermal throttle anymore.

I have a pretty cheap case, I think its the AVP Kolus.

 

My room, is pretty hot, like 23 degrees+

Yeah this is the case.

Apart from that, do you think it'll be possible to do some overclocking with the thermal paste on?

for sure, a 240mm radiator is plenty to overclock a 4 core CPU.

 

although I didn't notice that you said used in the original post, make sure the pump is working properly and that the tubes are hot when you apply new thermal paste and run the system. If the CPU is hot and the tubes are cold, you might have a different problem.

Well the tubes are very cold, but on the software it's saying that the pump is running at around 2300+rpm

at this time the tubes would be cold because the thermal transfer from the CPU is inadequate

Ah, alright.

Put on the new thermal paste and im not even getting over 40 degrees under full load!
