Worried about CPU temps - Page 4

post #31 of 78
While those numbers are high they are much better than what you had. What are your temps in normal heavy use? Like when gaming?

Well when running valley benchmark I'm in the 60s. Before, I had 100c after a minute or two.
I know temps are still high but the 390x is probably making things more difficult for the stock cooler as well.

As long as they stay below 70c when doing your most demanding jobs you are doing great. While I and a few people I know work our systems at 85-95% the majority of users rarely work their systems about 60% .. and then maybe hit 75-80% on extremely rare occasions.
When you are benchmarking you are running at or very near 100%.

Sense you only 'benchmark on rare occasions itis no problem with it hitting the 80's.

That's the thing, before, it went up to 100c with valley benchmark, the cpu was used around 15-20% max and i clearly hear the cpu fan going to max...It doesn't take much to use my cpu to 20%, adobe premiere, gtav and other games...i regularly play some l4d2 with a friend and this issue has probably been going on for a year, I just never really paid attention to it, never thought that the stock cooler or thermal paste would be an issue one day, why sell them with the cpu then? I guess I was naïve...kinda scary to think that my cpu was throttling down all this time and reaching 100c on a daily basis...

Yes, that is very scary.

Have you read any of "Ways to Better Cooling" linked in my sig? Like #5 on case airflow or #2 about what I use to monitor case airflow temps?

Glad you solved the overheating issue. Hitting only low 80s in a stress test with the stock cooler is not bad at all since it's still far away from the Tj max. Only 60s in gaming is even better.

How's your 390x doing now? Did you check max vrm temps after heavy load?

I'll do some testing tonight for the vrm temps, I haven't even had some fun with the 390x with the whole cpu heating issue. That sucks.
What I can tel you is that I find it amazing how the 3 fans work, watching hd vids on youtube and they're not spinning, the sapphire cooler looks sweet, a lot better than on my previous 6950.

And yes Doyll, I've read your post about cooling, I'm pretty sure that my CM 840 ATCS case cooling needs work. I have stock case fans, one 120mm rear, two 230mm top, one 230 front and added optional one 120mm bottom and two 120mm hdd fans. I disconnected one top fan because it rattles a lot. The bottom + cage ones are cheap CM fans that push 35cfm and I don't know if it's a good idea to have the 2 hdd cage fans because it might mess up or interfere with the bottom airflow. I've seen a video from jayztwocents explaining that you should have positive pressure, I don't think that's my case (no puns intended). I was thinking of getting new fans, the only 230mm ones I found are from bitfenix and I'd replace the bottom one with noctua s12, not sure I need p12 or f12

Talking about airflow, here's what I might do, is this any good?

would help if you indicate what direction the airflow is going to be pointing. assuming you are going with a front/floor > rear roof configuration, i would say you don't need the bottom noctua fan on the HDD cage. that area does not require additional airflow unless you have some seriously massive amount of cooling that needs to be done. the floor fan along with the top HDD noctua fan will be more then sufficient to feed your GPU.

as far as roof, i don't think you need 2 exhaust fan. 1 rear and 1 roof fan is MORE then enough exhaust. in fact if you remove your expansion slot covers, it's likely you don't actually need the roof fans at all. people underestimate the amount of airflow that a single exhaust fan can provide. the rest of the air can be passively leaked out of the case w/o being forced out by another fan.

ehume have plenty of builds where there is no exhaust fans at all and his temps are better then most people's builds.



but he likes to cut his cases and i'm not a big fan of cutting cases so i would say leave 1 exhaust fan in there to boost the airflow abit.

well I definitely wanna make sure my config is positive pressure or neutral. I disconnected one of the top fans which was making a terrible noise. Would've preferred to have 200mm fans, would've left me with more choice. Not sure how much Bitfenix spectre pro will be better than my CM stock 230mm fan.
And for the exhaust fans, that would be top and rear, rest is intake.
I'm still not sure about the HDD cage fans and bottom one, isn't the airflow from the bottom interfering with the cage fans? Maybe I should remove the lower HDD fan and upgrade the upper one to a static pressure NF-F12 or P12 so that it blows on the gpu.
