AMD FX 8350 getting unusually warm?

Hello. I've had an AMD FX-8350 that I've had for a good six months now, after 'replacing' my AMD FX-4350. (Putting it in my friend's build.)

I swapped out the Corsair 140MM Radiator Fan for an NZXT AF140MM fan, and it's popped up +10C at idle. I use it as exhaust, though I used the Corsair like...it pushed cool air from the room into the case. Still though, when I had the Corsair fan attached to the radiator (as an exhaust!), it never got this warm. It's idling at 43 - 44C and won't go down. I have it mildly overclocked to 4.3GHz. I noticed my CPU started getting warm on my other screen, as high as 60C when playing Watch Dogs, which I just got. I've never had it get this high, even when playing similarly intense games, like Crysis 3/Metro. It's never really budged over 48C, even at 4.7GHz with prime95 FFT test on.

So, should I pitch the NZXT fan? Because that's really seeming like the problem at the moment.

The CPU cooler is an H90 Hydro Series by Corsair.

That's quite a high idle temp for a 140mm radiator.

I wouldn't worry about the orientation of the fans for starters. Tests have shown time and time again that it makes little to no difference. In my personal experience of running both, air cooling the rad from outside of the case offered 3c colder temperatures at idle but also sucked in a hell of a lot of dust.

Did you remount the block when you changed fans?

It sounds like the fan isn't providing enough cooling. Which is a bit on the weird side considering neither the NZXT nor Corsair fan are really designed with Static Pressure in mind, on top of which, it's a thin rad.
You can go for a push/pull setup on that radiator, I would advise it, even if only for the bling bling...

(Or, added redundancy protection, if you want to give it a purpose. Two fans probably won't die at the exact same time).

Where do you live and what's the weather like? How warm is your room when the system is idle?

It's a tricky one because there really aren't many 140mm fans out there for Static Pressure. I've heard many bad things about the original Corsair radiator fans.
Since you say it was working exceptionally well before hand, it leads me to believe there's an error in mounting. A quick remount would provide a more in depth look at the situation. If the temps remain then my second guess would be those fans.

One does not simply take this damn cooler out of a C70 Corsair Case...it's a true pain in the ass.

But alas, I'll try a push pull method, and I'll post results. I know it's no incorrect mounting, because nothing is shaking, or lopsided.

Oh, like this.

Because it would just be blowing air out of the case, right? Idk.

I used to get no higher than 43 - 45C. It's just Watch Dogs, and yes, it's on Ultra, but it's never been this warm before and it's bugging me.

Haha ikr. Still, the C70 is a dream to work with compared to my old Zalman Z11.
If I see any plastic on a case again it will be too soon.

That setup looks good, I would definitely recommend investing in some quality Static Pressure fans.
(Have a look at the Noctua range. They're butt-ugly, in the sense that they colour match your butt and the stuff that comes out of it, but they work very well).

If that doesn't fix it, remount the block, it may have come loose or something.



Quite the contrary. 62c is the rated safe-limit for the 8350, and keep in mind games don't stress the chip nearly as hard as a regular stress testing.
60c is just a bit too high for regular gaming. It's safe, technically, but it says that a proper load would really push it into the red zone.

Alright, I'll give it a go.

And I would honestly just re-paint the Noctua fans. They really are stark-ass ugly.

I've got it back down to it's original idle temps.

It's now idling at 34C, says the BIOS, and HWMonitor and Speedfan are telling me 33 - 35C. So, we're good to go!

Two fans = better cooling anyhow. If I were in my old house, considering how cold it is in there all the time, I'd be having idle temps around 31C, maybe even 30C.

Thank you, by the way!
