Assistance in Troubleshooting a Heat Issue

post #1 of 8
Thread Starter 
I have a Coolermaster Cosmos 2 case, running an Asus Rampage 4 motherboard. i7-3930K cpu at stock (3.8 Ghz)

I've got an issue with the CPU temps, as the ambient is 77 degrees in the room, the temp gauge i have on the hose that is for the CPU loop shows 30.4 C on idle, but AIDA 64 shows a temp of 45 C, and the Asus OC Key shows a temp of 52 C for the Cpu.

In contrast, my 2 EVGA GTX 590's are showing 36 C for all GPUs in the secondary loop, again on idle.

Is my CPU just that hot? Or do I have a bad xspc mount? Not enough Rad?

Rad attached to CPU is 4 fan xspc (4 fans mounted on top pulling air through rad - not quite enough room to place fans on underside of rad).


Rads attached to GPU's are 2 double xspc mounted with fans on both sides (8 fans per rad).

All fans are running at 100% atm until I get my aquaaero setup for running it all, but I thought I'd solve heat related problems first to work out the bugs. smile.gif

Most accurate temp's should be listed in you BIOS, also check with Speedfan and Coretemp.

that is perfectly normal. Your water temp and cpu core temp cannot be the same. Heat is constantly generated by cpu and is moved to running water via cpu block. So equilibrium cpu-water delta is determined by the efficiency of heat transfer. Typical modern water block gives you 40-45 C of cpu-water delta at full load under moderate OC(e.g. 3930k @4.6). Under stock setting, I guess your number is totally fine if it is measured at full load.

This is at idle though, not at full load...

Core Temp shows the following (image attached):

That's not normal then. did you measure the full load temp? The likely suspect is bad mount of cpu block. I would try remounting the block and see how it works.

I didn't measure full load, as this idle load temp has me concerned that it will damage it in the process. I'll see what I can do about getting the xspc raystorm reseated with the artic silver again.
