CPU Temps, Assess, Diagnose

[rodion.zissou]

Hey there LTT community. It's been a long while since I've visited or posted, but I'm hoping for some help.

 

I built my rig about 1.5 years ago. I've regularly opened it and dusted it best I could without removing fans, radiator, or anything else for that matter aside from case fan filters. Anyway, I recently did a clean windows install, added some storage and did some stress tests as a check up. I ran across some higher temps than I remember when initially dialing in my 4790k to 4.7ghz. I was hoping you could give the screenshot a look and share your thoughts. Should I be focused on package temp vs individual core temps? What about vcore temp? Why am I seeing such large variations between the 4 applications and there temp reports? Do my CPU temps appear to be problematic? Should I check my AIO's fill level? 

 

I ran Aida 64 for 5 minutes for screenshot.

Stressed CPU, GPU and MEM for worst case scenario effect.

My PCs components are listed in full here.

In that year and a half, have you flushed your loop to replace your coolant and changed the thermal compound and thermal pads (provided your GPU is w/c'd as well)? Sounds like you might be due for that. Take it as an opportunity as well to get your fans as clean as you can.

I've an NZXT X41 AIO (140mm Rad) run in push exhaust only cooling cpu. Is it normal to flush, replace coolant, replace thermal paste etc on an AIO 1.5 years after install? Any chance you could answer my other questions? Thanks for taking the time.[emoji5]

With an AIO it's maintenance free so you don't need to change or add fluids, thermal paste after a few years isn't a bad idea since it can dry out, but at around a load of 77C it doesn't seem that bad with a core voltage of ~1.350V on a single 140mm watercooler.

Where are you getting the 77C from?

Just a rough estimate from your current (value) temps on the 4 CPU cores.

Ah, I'm thinking the max temps are more relevant as far as diagnosing a possible problem.

Well your max temps are a quite high at 90C+ but as long as it's averaging that ~73C on the graph your still pretty good. Random spikes can occur at times but as long as they aren't constantly running that hot you should be fine.

Ok, thanks.

So you don't need to blow all the dust out of the fins?

If there is a carpet of dust, well there's your problem!

No dust carpet. I regularly air-can the rad, fans, filters, case etc.

Filters.... remove them, remove the brick wall that is the dust filters...
