Noctua Nh-D15 & Prime95

[DrexWOlfHAM]

Hi,

I don't know much about Building computers or compatibility issues . my current build was prebuilt and bought in 2012. only added new graphics card, and the cooler now.

I just installed new fan Noctua NH-D15 from Corsair Hydro Series H55 Liquid Cooler, and i was testing on Prime95 to see temperatures.

But after 3-5 mins with Prime95 running, my pc crashes and blue screen, saying
"Your pc ran into a problem and needs to restart. We're just collecting some error info, and then we'll restart for you. Clock_watchdog_Timeout"

The first time it rebooted itself , second time froze on the blue screen.

Cpu Idle temp is at 40c

When Prime 95 was running the cores going up slowly one or two hitting 60c . then pc would crash/freeze.

anyone would know what the problem could be or how would try to fix ?

my pc specs.

Which version of Prime95?

Hi,

I installed the correct version of prime95 now the 26 one and the testing works fine on there , left for 1 hour half going and no crash.

But Temperatures still seem high at round 41c idle , would be anyway i can reduce ? When the Blend was running this time the max Temp the CPU got to was 69c then would go back down was around 64c most time the cores. at 100% cpu ussage.

I thought this cooler would work better, then previous.

DrexWOlfHAM,

For thermal testing you should run Prime95 version 26.6 Small FFT's, which is a steady 100% workload that has steady Core temperatures. The default test, Blend, is a fluctuating workload for testing memory stability which has fluctuating Core temperatures.

What is your ambient temperature?

 

[DrexWOlfHAM]

Hi,

I ran the Small FFT's and When it was warming up it got to max 71c and Drop back down as test went on.

The Ambient Temp 22.5c

You have an excellent high-end air cooler. Your ambient temperature is normal and your Core temperatures are fine.

Here's the recommended operating range for Core temperature:

80C Hot (100% Load)
75C Warm
70C Warm (Heavy Load)
60C Norm
50C Norm (Medium Load)
40C Norm
30C Cool (Idle)
25C Cool

Core temperatures up to 80C are safe.
