CPU heat issue

[jollander]

I'm having temp issues with my 4790k. It idles around 32% but whenever i start a stress test it goes to 60-70c in less than one second.

During a 5 min test it jumps between 67-73 degrees, as in it goes directly in between them without really stepping up or down.

As a comparison, whenever i use furmark to test the gpus it takes 15 minutes to go from 35-ish to 41 degrees, and it's a steady rise.

 

Setup:

4790k @ 4.6Ghz 1,29v (same temps at stock, however)

2x 689 SLI

360mm & 140mm rads

 

 

I've replaces the thermal grease and used the pea method. Also made sure that the waterblock is properly attached. 

Any ideas on what i can do? Pleas help :<

thats not a massive amount of rads for that system, are the gpu and cpu on separate loops?

[jollander]

Same loop. My original setup was the 680 sli and an overclocked amd 8350 @ 4.7ghz and only the 360 rad. It ran in the high 50, low 60s.

 

But the rads cant really be responsible for the fact that the temp goes from 32-70 in less than one second, right?

no probabably not, try removing the overclock for now, run some more tests and see if you still get a temperature jump

What program are you using to monitor temps? I personally always use hwmonitor but ive hard coretemp isnt bad. If you arent using either of thise it couldnt hurt to test one out and see if you get same results.

What program are you using to stress test? Please use AIDA64 for your CPU, prime95 is not properly suited for your CPU.

 

You left out what pump you are using. Nothing short of a D5 should be paired with a loop consisting of a CPU and two GPUs. GPU SLI connectors and blocks are restrictive. 

 

Are you using adaptive voltage for your OC? If not please do so.

Using HWmonitor and Intel ETU

I was using Intel ETU for stress test.

I've installed AIDA64 trial and it jumps straight to 65c. It doesnt jump between 60-70 as Intel ETU did, however.

 

As for the pump, a Laing DDC with a res combo. 

 

I was using adaptive to begin with but changed to static to see if there was any difference. Could you explain why I should use adaptive please?

 

 

I should probably mention that I've been an AMD user since forever and the bios confused the crap out of me here, so i used the pre-made overclock settings that the Maximus vii Hero supplied. I recall seeing Linus or Slick mentioning something about the results being worse with those.

The DDC has excellent pressure but not the flow and both are needed for restrictive loops. 65C is alright, not really a problem for your loop. Now what are your GPU temperatures?

 

You should use adaptive because it only give just enough voltage for the given frequency thus aiding in lowering the temperatures and increasing the life of your CPU. Having manual voltage give the set voltage weather it is 1.2v or 1.3v all the time no matter if you are in idle or load states.

well, my 4700mq behaves pretty much same as you say, it jumps instantly to certain temp then raises slowly as laptop heatsink can't keep up as well... wouldn't pay much attention to it... i assume it's just limit to how fast it can transfer the heat out, when it bumps boost to max. 

 

see if it runs cooler without any overclock, but personally i wouldn't be too bothered by it... it wouldn't really be overheating, though it seems a bit high for water cooled set-up...

Great, so I shouldn't be worried about the jump from idle to load? My GPU temp is 44c during a test on furmark.

 

Thanks for the info, will set it back to adaptive.

Not really, if the temperture just was in the high 70s to 80s then panic.

 

B) about the adaptive.
