H100 temperature question

[melchiorvester]

So I have a H100 and get around 35-40C when idle and the outside temperature is around 23C.

 

I have two NF-F12 in pull config with the speed setting on the block at max (3/3). 

 

I haven't ever replaced the thermal compound on the block since it was installed which would be around late 2012 when I first built it.

 

I also get idle temperatures on my MSI 7950 of 47C and could also replace that thermal compound while i'm at it.

 

Do you think it would be worth it to replace the compound on my CPU block and my GPU?

Idle temperatures don't really matter, it's load temps that do.

What would be best to test my load temps besides prime95 since I heard its bad for some processors?

aida64 is good, and intel's exterme tuning utility is good too.

Intel XTU, aida64, cinebench

I'm doing a stress test with aida64 right now

Run it with CPU, FPU, and Cache checked.  Leave memory and everything else unchecked.

 

Stay away from FPU only unless your are trying to get the CPU hot on purpose.

I already have only those checked when I first started the stress test. I'm going to let it go for 20mins

So this is what I ended up with.

Once you've loaded the pictures into the browser, you need to drag them up into the dialogue box until you can see that they are visible.  Then post.

 

There's a glitch going on within the LTT forum right now, but this temporary fix should tie you over.

Your temps look fine, but if you changed the thermal paste you would probably see an improvement.

Agree.  Might actually reduce disparity between core temps a bit as well.

 

@melchiorvester If you are still interested in why your idle temps are a bit high, you may want to investigate your idle voltage and whether or not SpeedStep is working correctly.

What is speedstep?

It scales your CPU speed and voltage up and down from idle to full Turbo speed based on the load of your CPU.  

 

If you go into your Power Options within the Control Panel, make sure that "Balanced" is selected.  If you have it set to "High Performance", the CPU will stay at it's max frequency, even when you don't have a load.  This will in turn cause your "idle temps" to be a bit higher because your technically not idling.

 

If you set your power options to balanced and it's still not scaling up and down, you need to verify that you have SpeedStep enabled in BIOS.

 

You can verify your CPU speed in AIDA64 or with CPUz.

 

If you've overclocked and set your voltage manually to whatever voltage you use, voltage will not move up and down as needed.  If you have manual voltage with SpeedStep enabled, the CPU will continue to scale up and down, but the voltage will stay put.

Well I set it to "balanced" mode and didn't see any change to my clock speed at all. I have a overclock and see my voltage moving up and down.

 

I see random jumps from 1.6GHz to 4.1GHz

You're confusing me.  You say "I see random jumps from 1.6GHz to 4.1GHz" but said that you don't see any clock changing? 

[melchiorvester]

Oh sorry... What I meant to say is that I see a clock change of 1.6 to 4.1 range. When I don't do anything on my computer or light stuff I see the lower end of the numbers

[done12many2]

Sounds like SpeedStep is working fine.

Right. I still don't see much difference in temperatures with that change and I feel like if my clock speed and voltage is lower then it should result in lower temps?

Yes, you should. Our setups are completely different, but my CPU idles a within a few degrees of ambient room temp.  Yours is fine, but I agree with @Enderman that some new thermal paste could improve things.

Because you have a custom loop with lots of rads right? 

 

I will try putting on new thermal paste and do another stress test after that. I already have Noctua NT-H1 compound
