Temps are actually higher after installing new heatsink.

[dto1984]

This is frustrating. I got tired of the noise caused by the stock heatsink for my fx 6300 and bought a Cooler Master Hyper TX3. I installed it, and the fan itself is nice and quiet, but the temps are nowhere near what I was expecting (under 60 c during load was my goal; the stock cooler was doing about 71 c) and are in fact higher than with the stock heatsink. The TX, at it's best, is doing about 77 c under load. Playing Alien Isolation for about 5 minutes just now got me about 81 c. I'm not overclocking.

I assumed it must be something with the installation. I watched a couple Youtube videos and twice pulled the heatsink out, cleaned it off, re-applied thermal paste (I'm using the cooler master paste that came with the heatsink as I ran out of Ceramique 2) and reseated the heatsink on the cpu. The heatsink itself appears to have good coverage over the cpu. I applied only a small pea shaped dot of thermal paste on the cpu and should not have any air bubbles. Airflow around the case is good.

Any suggestions? Right now I'm pretty much fed up with the whole thing and ready to return the TX.

Ehh, the tx3 isn't particularly great: http://www.guru3d.com/articles_pages/coolermaster_hyper_tx3_review,6.html
What's your ambient room temp though? if you live in a kind of hot place/warm room those extra degrees seem reasonable.

But AMD cpus do run pretty hot as well...

Room temperature right now is about 70 F. My tower is close-ish to a heat vent (the vent is in the floor; the tower is about 3 feet above it on my desk), so I suppose that might influence the temps, though I still don't think that should be enough for them to be higher than the stock cooler.

I did just notice one of my case fans isn't spinning, so that's definitely part of the problem. I'll see what happens when I get that fixed.

Update: Fixed the case fan. It might have knocked 2 c off in HW Monitor. However, since HW Monitor can be unreliable, I also checked thermal margin in AMD overdrive. I'm getting less than 10 c per core under load, which is pretty alarming.

Still baffled by this. The outside wall of my case the 6300 sits next to was always fairly warm with the stock heatsink. With the TX, the side of the case is barely hot at all even under load, and when I open my case, the heatsink is hot to the touch, which indicates it's working properly. My case fans generally blow out cool air when I'm not doing anything to put the cpu under load, another thing the stock heatsink wasn't doing.

I'm not so sure at this point that the problem isn't the heat sensors on the mobo as nothing I've seen suggests the cpu is actually overheating.

Are those socket temps or actual core temps? If they are socket temps then that is perfectly normal.

 

[helpstar]

which tool do you use to get the temp?

try coretemp and realtemp

Coretemp is in pretty close agreement with both HW Monitor and Speccy. The temps consistently fluctuate by about 8 degrees and all three programs are showing somewhere between 43 c and 53 c while using Chrome and having four tabs open.. There are also several programs running in the background (Steam, Origin, antivirus, Raptr, those kinds of things ).

Did you regulate the fan speed in bios or with a tool before?

Reseat the cooler and use a bit less or more thermal paste
