Are these temperatures normal?

[Mercuryaces]

So I just got and installed my corsair h100i pro and started to stree for a little over an hour using Aida 64 with all boxes checked off. My CPU during this stressing reaches the low 80c's using the "quiet" performance mode of the AIO. Are these temps good?

[mxk]

I'm pretty sure you're fine. AIDA 64 and other synthetic benchmarks like Prime 95 usually go pretty hard on the CPU (usually more stress than anything you'll actually be using the CPU for) so it looks ok to me.

Depends what's your CPU I suppose, but over 90c's you should start to worry.

AIDA64 pushes your CPU hard, I get 84c on my 8700K with  360mm AIO.  You're fine.  It's the ingame temps you should look at realistically.

Cool. As far as I can tell, I get low 50c's while playing blackout, which is a pretty CPU intensive game.

That is perfectly acceptable temps

And 84c is acceptable while stressing the CPU and FPU as well as GPU and Memory simultaneously?

Definitely.  It's a good bit under the thermal throttling limit, so if you're going 100% balls out and still have some heat headroom.... all is good.

It's a bit on the higher end, but nothing to really worry about. If you want to find out what your cooling is actually capable of, set it to whatever the high performance mode is called instead of the quiet mode.

 

I'd start getting worried at 95-ish

That's very high, if it's 95 it's probably therm throttling like crazy and it's not going to last very long

Thermal throttle is not the point at which temps begin to be unsafe, silicon degradation can still happen a few degrees or more under it. 85C or under is usually my recommendation

it should only start thermal throttling at 100 I believe? I wouldn't want it running at 95 under normal load, but a full on stress everything test?

Thermal throttling as in shut down the entire system, yes. At 90 the motherboard starts to forcibly downclock the CPU.

While people spout the 85c number about, where is the engineering white paper that shows this as a degradation point?  Where is the temp/lifespan graph and curve?

 

This is about the closest I've seen, where even Peugot Systems says it's fine to run a CPU at 80-85c for extended periods and it doesn't much impact CPU life.  So then at 86, BAMM the CPU is half-lifed for shit?

 

Seriously, even if 85c meant half the lifespan,  CPU's have such long lives (without manufacturing failures) that it really doesn't matter.

Btw, only when stress testing do folks hit that temp anyway, so it's kind of moot all around unless you're doing some weird shit.

On my FX 8350 space heater with the H100i GTX AIO I only hit a max socket temp of 56c and 41c CPU during TORTURE tests (prime95 and Unigine Heaven running simultaneously for 1 hour).  (pump set to extreme...you should try pump to extreme it doesn't change DBa imho and fans to 70%) normal gameplay I put my fans at 40% for near silence.

 

Im going to say that this is WAY to hot.  I would check my thermal paste application and ensure Ive tightened everything down appropriately.  Id also check for an air bubble in the pump housing.  Use Extreme and let it try to force that thing out (and ensure you have something either hoses or radiator higher than pump so air traps there) or take the AIO off and give it a good shake with radiator high so air bubbles go into the rad.)

You are at the tipping point with those temps.  With what you are describing you either have bad airflow, or a lack of it.  That AIO should smash that chip at 100% load.

 

I use a 120mm CoolerMaster Lite AIO on a R7 1700 and it doesn't even hit past mid 50's Celsius if I recall correctly during Prime 95 lol.

Rerun that with Prime95 and AIDA64.  No CPU will stay that cool under stress testing.

That goes back to the 5k86 era, it was said you'd make the CPU catch fire at 85 degrees, it's the same reason people began worrying whenever it hit 60 degrees which was high for that kind of CPUs (also heatsinks were tiny) and so that got to this day where you can still find folks saying 60C is a dangerous temperature.

 

Hitting 60C under load stopped being dangerous with the Pentium III

So Prime95 and AIDA64 at the same time?  Prime95 uses more voltage than AIDA, but AIDA can cause higher temps through FPU stressing from my understanding but Id gladly do the run, my first rig in my sig is meant to be cold.   (And since FX shares FPU, Im not sure Ill get that hot since it will likely only run 4 cores - Ive never used it but will do some tests over this weekend)

 

Can you run them both at the same time?  I have to get Unigine going first then start prime just because of all the system resources being so heavily utilized.

Just go to my proven screenshots on this forum in my TG Kryonaut review.  I have the timestamped screenshots.  Yes CPUs stay that cold.  Specifically cases like a HAF with 14 fans moving air.

 

EDIT here I pulled up my screenshot for you - maybe your airflow sucks lol

How cold is your room? A minimum CPU temperature of 16 degrees to me indicates that your room has to be substantially be below that. At least in most EU countries, that is below the minimum temperature that is considered a suitable living environemnt.

Can you help me interpret this graph really quick? Does the flat yellow line indicate the highest temp it got to, while the zig zagging line is the actual live feed of temps?

That's cold boot after applying new Thermal Paste - my ambient room temp is set at 70F (that's 20 or 21 Celsius) my PC is next to a large window and its winter here.  So that is the Cold Boot offset you are seeing.  Likely closer to 60F (which is 16c) near those windows.  But its not "intaking" off of it, its side by side my Ryzen 7 rig about 3 feet FROM the windows.

 

These temps are with TG Kryonaut.  Prior on 12.30.18 (have those screenies as well) I was at 59c socket and 46c CPU.  TG Kryonaut is the shit.

 

Seriously, read my sig and you will see how many fans are moving air in there.  Look up the cooler master HAF cases - you will see why my CPU is cold.  Because the only air that's being introduced to the radiator is room temp.  Its moving air in as fast as its possible and evacuating it as fast as its possible. 

 

How many fans yall got?  I mean I even have 2 40mm fans dedicated to my RAM lol.  I have 1 80mm fan dedicated as intake on the SSDs.  I have 1 200mm intake dedicated to the 2 GPUs.  I have 1 200mm dedicated to just intake.  Running with an AIO that's dumping the air OUT of the case.  Ive modded the case to remove the HDD brackets to ensure no blocking intake.  This IS a science lol.

At the top of that bit is a legend for how to read it, explaining what each line is. On my screen it's this:

To me that's your CPU temps

 

I just did a 1 hour AIDA64 stress test with CPU and FPU maxed.  Here are my temps and how they would potentially correlate to yours (compared to HW Monitor in my SS and iCUE)

These are my temps with a 240mm AIO on a 125w processor.  That's why I believe its to high.  Something isn't right at least compared to what it could be.
