Weird peaks during load

[kinglevel]

Hello

 

Long story kinda-short..

*After my PSU decided to explode with a small bang, i made the decision to swap it.

*All booted fine, but after a while the machine started to abruptly automatically turn off.
*I suspected that the motherboard was fried from a peak from the broken PSU, so i also swapped the MB.
*With new MB and also PSU, the same automatic turn off happens again (I am starting to suspect the cooling)

And lo and behold, under a load test i discover this:

 

Load Graph

 

I have manually set all fans to maximum, but these peaks are happening at random.

 

Any ideas?

your graph has no numbers so we can't know if it's normal or not. it's fine for things to heat up if it's bellow 100C

peak was at roughly 80.

It is ok, yes, but i have never seen temps jump that high for brief moments

temps always rise sharply when load is applied. almost a 1 to 1 with the load % graph actually.

But these peaks are in the middle of the load test and not when load is applied.

Load is applied 100% and then temps are skyrocketing at random during the load.

you clicking test doesn't mean the load is instantly applied. there might be a loading time getting the test in ram before the CPU starts working. there might be lower and higher intensity parts to the test.

and windows doesn't report usage in a way that is related to the amount of calculations happening. it's more like it's telling you if the queues are occupied or not.

 

if you have monitoring software like HW_monitor or HW64 you'll see they tell you how much power you're CPU estimates it's pulling at each moment. this is much more closely correlated to the actual computational load.

You're probably being distracted from the real problem. Squinty is right. Do you have spare parts or another computer to test stuff with? If so, try swapping the CPU and RAM separately.
