HWINO reporting temperature much much lower than SIV under Prime

post #1 of 2
Thread Starter 
Which to trust?

It seems hard to believe that my CPU would get to 71C in a very short time with a 480 + 360 radiator loop just for the CPU, even with low-speed fans, since I'm on just 4.4 GHz with an 8370E that's lapped. That's what SIV is reporting. The pump is working because I can feel it vibrate. I unplugged it just to be sure. No vibration then. When I plugged it back it I heard churning (although I haven't seen any water movement in the reservoir since I added the 480mm radiator) for a bit and felt the vibration again.

It can't be dry TIM because I just applied it again (EK Ectotherm) after lapping off the Liquid Pro.

I have a 140mm fan on the VRMs, a 140mm fan blowing toward the northbridge, and a 140mm fan behind the socket.

The other oddity is that HWINFO's temp jumped from 21C idle to 52C when Prime started nearly immediately. This makes me wonder if there is something preventing the heat from being transferred from the CPU. I ran Prime a bit longer with HWINFO and the temp did not climb way high, though.

I ran Prime again and this is with two windows open at 50F outside so the ambient temp is low. HWINFO reported 55C after about a minute and then the temp started to drop which suggests some sort of throttling happening.

Something is not right.

edit: My EK-XRES 100 DDC MX 3.1 PWM (Laing DDC 3.1 PWM 6W) pump's speed range, according to HWINFO is 1721 RPM minimum to 2872 maximum. Since I have no other fans plugged into the motherboard I assume that has to be the pump since it's PWM cable is plugged into the CPU header. It's odd the HWINFO reports that as "chassis" though.
