I have an athlon x4 840 and I managed to get a cooloc from 3.7ghz up to 4.3 (with a little extra voltage). But when I run a stress test, my cpu drops clocks down from 4.3 to around 1.7ghz. I am using amd overdrive to keep an eye on the temps and the thermal margin is about 30C under full load. What should I do?

One option is to use an infrared thermometer. Take off the side panel from the box and point your desk fan right at the motherboard. This way, the power supply's voltage regulators get cool air flowing over them.

Your power supply might have more heat problems than your processor.

My VRMs don't come with a big metal block to cool them down. So how can I figure out what the temperatures are on these parts?

One simple fix is to use an infrared gun to check if it's too hot, then take off the side panel of the case so you can point your desk fan right at the motherboard. This helps make sure there is enough cool air reaching those power rails.

I have molex fans. I will try them out to see if they fix my issue.

I figured out that VRMs (very red master) are the main troublemaker, and I even tried using a fan but failed because there isn't enough room for it. Can I find better ways to keep them cool effectively?
