Are those temperatures ok for i7 4790k? stock overclock only

[11killer34]

So sometime back i had problem with high temperatures and computer crashing. My i7 4790k was running on intel stock cooler and i had case with 3 fans, which couldnt get rid of heat of my gtx 1080. The temps were going up to 95-100 degrees when running stress test, or up to 85-90 degrees when playing games. 

 

After replacing stock intel cooler with hyper 212 evo and replacing pc case with rl06 with 6 fans and replacing normal termal paste with arctic silver 5. I ran stress test for both i7 4790k and asus gtx 1080 a8g strix (because its heating the case).

 

Under stress i managed to get 72-74 degrees, max 76 and 30-40 degrees when idle. I heard that 80 degrees is already hot, so are current temperatures ok, or should i upgrade anything else? because i have no more ideas what to do. i7 4790k is stock overclocked.So 4.0 ghz-4.4 (turbo)

That's fine. Intel's processors start going into thermal control when it approaches 100C.

 

Also such tests are unrealistic workloads for most people. They're only useful to either see if an overclock is stable or to grab data points on the viability of your cooling system.

Your numbers are healthy. Its doubtful you'd ever be taxing the PC in every day use in such a way that you'd hit those max temps anyway. 30-40 degrees idle is also spot on. Nothing to worry about.

For stock clocks this is definitley not a good result, not even for a Devil's Canyon chip. I'm currently running an i7 4770k at 4.2 GHz cooled by a 120 mm aio and the hottest it ever gets is 57°c in the Intel XTU stress test.

 

But on the other hand your temps aren't a desaster either. Preferably they would be lower, but low 70s isn't hurting your cpu at all. Its just unfortunate, because the 4770k/4790k is still a very decent cpu and overclocking works wonders in terms of performance. According to Hardware Unboxed it will bottleneck a GTX 1080, though the margin can obviously be minimized by overclocking.

If you want to keep your 4790k for a couple more years I'd say a 120 or 240 mm aio watercooling unit would be a very good investment.

 

Also maybe check your BIOS settings, some mainboards use weird default profiles or tools like llc when they detect certain cpus to "increase stability" even if you don't ask them to and in such a case you'd have to disable it manually. I've had this happen on a MSI board once, but its also a thing with other manufacturers.

Thats normal temps for 212- What are your voltages like when stressing? Screenshot doesn't show correct numbers, I think they are under mobo.

I switched my thermal paste from arctic silver to akasa pro-grade 5022 (i was advised by computer specialist). And im getting now maximum 65 degree celsius under all stress loads at the same time.

With same testing and all? I would call mounting being issue rather than paste. Or that paste wasn't spread enough. Thats way too big change, when actual testing made by tech sites has shown max 5C difference between quality pastes. You are talking about 10-15C change.

Yes and also i forgot to put washers so few degrees thermal paste and few degrees washer fault.
