I would like to consider myself as a bit of a PC aficionado.. But these temperatures that I'm getting with my new build are getting a little ridiculous. I've tried reapplying Arctic Silver 5 3 times, in varying consistencies, and I've tried tightening/loosening the heatsink to the mount, yet nothing makes a difference.
Current Temperatures (ambient room temperature 24 degrees Celsius)
I am considering updating the bios incase it's a flaw with the sensor. My old Q9400 used to run around 28-46 degrees with a similar cooler in the same case, with the same thermal paste and general installation technique.
What do you guys think? Doesn't 70c seem a little high for a processor that apparently "runs cool"?
Hmmm... those temps aren't good. If you touch the heatsink, does it feel very hot?
If you're sure the heatsink is seated correctly, and making good contact it must be a sensor error. Does it say the same in the BIOS? Try running Prime and unplugging your comp and quickly entering the BIOS to see if the temps are similar.
Well Arctic Cooling isn't exactly known for its cooling performance. I used to have a Freezer 7 Pro, and it really wasn't much better than the stock heatsink.
Arctic Cooling is in high regard here in the UK. Their products have had some excellent reviews. Although I'm extremely disappointed by this CPU cooler specifically, because it's the first Arctic Cooling product I have purchased... And it appears to have failed completely.
The CPU cooler is seated correctly. I've also applied the thermal paste correctly. Those temperatures were reported with prime95 running for an hour with an ambient room temperature of 24 degrees Celsius and the both sides of the case attached. I also tried running Prime95 with one side of the tower off, and the CPU cooler was very cool to touch, as was the ram heatsinks and the rear/top fan, but the CPU temperatures actually increased by 3 degrees C. I honestly can't see or feel where this heat may be coming from. This is the first build I have ever had that has had such high temperatures that are completely inexplicable! I'm starting to think this could be a slightly dodgy sensor on my Asus P8P67 motherboard. But I'm also considering the possibility that this is just a really bad CPU cooler. I'm currently looking in to a water cooling solution instead.
I'll post pictures of the inside tomorrow. The 250mm fan above and the 120mm fan to the rear should surely assist the 92mm CPU fan in dispersing the air from this "high end" heatsink.... Though something seems to be failing in my rig!
We'll get to the bottom of it... I'm sure.
EDIT: BIOS temperatures also average 50 degrees. I'm running the fancy new Asus BIOS. And I think it runs at the stock speed without scaling back CPU clock speed. So at 3.4GHz, I'm hitting around 50-54 degrees, which really sucks with an after market cooler in my opinion!
