pc dust clear out Problems with PC speed after cleaning

[Rabolisk]

So, I might have made a dumb mistake. I opened my pc case cleaning for dust with a brush. I removed my CPU fan to remove any dust and connected the CPU fan again. Problem is I noticed I didn't have any thermal paste (forgot about it) and I noticed most of the thermal paste was gone anyway. That's because it's an old PC I got in late 2011 (it's an i5 2500) and I never removed the CPU fan since it was assembled 8-9 years ago. Now I noticed the CPU is significantly slower. So, what could be the reason?

 

* I didn't reapply thermal paste. But it was running fine before I removed it and the thermal paste ran out

* I didn't connect the fan properly.

 

Also is there any reason to test if the CPU is indeed throttling because lack of cooling?

 

Thanks.

use a program like hwinfo to check tempatures of the cpu. not reapplying thermal paste could defiantly be a cause of cpu thermal throttling even if the fan is spinning correctly

thermal paste doesnt disappear so did it ever have it?

Yes. There were a few blotches as if it dried out. It's been 8 years.

ok well you definitely need to replace it and not just stick the heaksink back on

I will do that as soon as it arrives. The thing is it was running fast right before I cleaned the PC. So could it be something else?

yeah did you check the temps yet or are we waiting on something for that

Yea. Just checked my temps they're all between 80-100 ⁰C. I guess that is too high?

 

 

 

Yea
