Vrm temps

post #1 of 8
Thread Starter 
I recently oced my sig rig to 3.4 at 1.400v. 17x201. I have the zalman cnps10x performa giving me great temps at 32 at full prime95 testing. With the cooler I have I don't have direct air blowing on my vrm heats inks but I do have good case airflow. 2x120mm zalman intake fans and 2x120mm zalman exhaust fans (stock case fans) I added a cheap 140mm eBay fan wich gives about 35cfm for intake. All running at 100 speed.


Now for the question. Should I be worried about my vrm/mosfets temps on my rig. Is there a way to monitor the temp in software with my m4a78t-e.

Thanks in advance for your help

Oh and I jammed the sensor from my front panel temp monitor between 2 fins the the vram heatsinks and it peaks at 40 degrees. I dunno if it's a reliable temp or if it's high

The m4a78t (no e) is on the VRM list as "safe", but the -e does not appear on the list. I would say it's relatively safe to OC, as it does have a heat sink on the mosfets, but if you really want to make sure things are safe, invest in a thermal gun, so you can check all the points with more accuracy. I did, and found that there were points on my motherboard that were reaching unsafe temperatures with my OC. This prompted me to put a few mini heatsinks on some different hot spots, lowering overall temperatures across the entire area.

However, if the temperature sensor is accurate at 40c, I dont think you have anything to worry about, especially with CPU temps of 32c on Prime95... you sure you got those numbers right? Thats really low.

Should I try another third party app to make sure??

If you can get a temp reading from very close the chip, then that would be much better than what you are doing. The temp sensors in boards that give you a MOSFET temp readout have a thermal diode close to them, not physically located on the chip itself.
