FX 8350 idle running 72c on hyper D92.

[erosion139]

I recently acquired a Hyper D92 from coolermaster expecting better results than stock. I installed it properly with the correct mounting hardware and fired it up. The temps looked good running at 27c on idle. Or so I thought. Playing games that maxed it at 50% load got it really hot. 75c that is, so I stopped the game, No temperature difference. Its as if the cooler refuses to work after it hits a high enough temperature. Still 70, 68, 67, 67, 67.. It would just stay at that. The CPU is only at 6% load so nothing should be heating it up that much. Honestly the stock cooler worked better than the D92. Something is wrong because when I feel around the heatsync the fins are cool, The heatpipes are warm, and the aluminum block is really really hot. I blame the heatpipes, are they too small? Or have they just stopped? Im stuck, This is supposed to be a temporary cooler before I go water. But I didnt expect these temps.

Did you replace the thermal paste when you replaced the stock cooler? Are you sure the retention bar that goes across under the heatsink is secured to the plastic on both sides of the socket? Just placing the metal holders on the plastic clips isn't enough, you have to torque down the handle to push it against the CPU.

Is the fan spinning?

Okay, Well first option is to remove the thermal paste and re apply use 90% rubbing alcohol or higher with a coffee filter and apply a pea size of thermal paste. And you said that its at 27c on idle at first? But now its 72c on idle? That is crazy to go from that to 72c on idle. I would try what I suggested and if that doesn't work let me know.

Yes. The heatsync has been mounted properly, The thermal paste was re applied twice with no luck. The heat conduction to the aluminium block is very good but the heatpipes are not doing the job.

Hey there Erosion,

I have seen friends with AMD CPUS, and personally, I think they are waste of money. Intel is 200000000000000000% better, and AMD is just that hunk of silicon that can't be contained.

Replace your Damn CPU,

Thanks!

I will try remounting again. I will use a conventional rice grain size rather than the X method I used before. Either way it should only be a 2c difference right? Its been tested before.

Do you identify as a chambered intel fanboy?

Ok I have reinstalled the cooler with a Pea sized dot in the middle. Tightened it down respectfully and ran handbrake as a benchwark. The cpu was climbinto 70c slower than last time but it still got there. Also took a long time to get it down to just 49c on idle.

 

[erosion139]

Now It is climbing to 54c with only 10% load. (I just put the side panel on)

 

[erosion139]

Scratch that its at 70c right now. Not playing anything and runing 14% load.

Turn it off and put the stock heatsink back on. While Intel is comfortable at that temperature, AMD CPUs need to be kept at lower temperatures.

Just out of curiosity, is the heatsink plugged into the CPU FAN header? If you plug it into a chassis fan header, the fan won't speed up when the CPU starts to warm up.

One fan is plugged into the CPU fan header and one in a system fan header. Both do speed up when the heat gets high. (I control both of them and even pushed them to 100% with no luck.) I reverted back to stock and, WOW IS IT BETTER! Not only do I get better idle temps but also the load temps. 50c MAX on 100% load, not 70c like on the tower. BTW the cooler was indeed mounted correctly but no matter how far I pushed those fans it would just climb. I am leaning towards the heatpipes for the failure. Either way I suppose I can survive on stock until I can get water.

This isn't really that surprising. The Hyper D92 has a hard time with my brother's Phenom II X6 1090T which is a 125W CPU just like yours, but the FX series is known to run warmer because the cores are packed more tightly together. I had to undervolt his CPU to keep it from overheating.

I got it used on Craigslist so I didn't get a stock cooler cooler with it.
