In general, MOSFETs come in square black packages about 4mm square. The most effective way to identify overly hot components is with your finger. If you can't hold a finger on it, it's too hot. If you jump (YOW!) it's way too hot. If it raises a blister, it's about to fail.

Quick question on the case fans. How quiet are they? Or would you recomend getting some better ones? something like an AcoustiFan DustProof Quiet 120mm Fan? Or a Zalaman running on the 5v line? The stock Antec TriCools are pretty loud. I replaced mine immediately with AcoustiFan DustProofs, which w...

I use a Phantom 500 in my P180 with a Nexus at 5V (650 RPM) in the lower chamber. This is enough airflow that the HDDs run 33-37C depending on room temperature, and the PS fan never comes on (the PS heat sink stays below 45C). This fan cannot be heard at all with the case closed.

I replaced the stock TIM with AS5 on my Gigabyte X800XL passive and noticed the heat pipes were noticeably warmer to the touch, implying better conduction. I didn't measure temperatures, sorry.

The stock TIM was quite thick and didn't look to me like it would be particularly effective.

I have four orange Nexus fans, and two were unreliable starters at 5V. I run two of them at around 6V with inline resistors, and the other two with NMT-3 controllers, which start at 12V and drop to 5V.

This is unlikely to be a CPU TIM issue.

As for which instructions to follow, use the Arctic Silver instructions (a rice-grain-sized blob in the center of the CPU). The AMD instructions are for a more generic greasy TIM; AS5 has lower viscosity than most and spreads well with just a bit of pressure.

ok, it's cavity air resonance I was thinking of, tho it's true that just having a fan in the lower chamber is probably enough to excite the chamber's air resonance anyway. With a low speed, low vibration fan, it's usually not much of a factor. Depends on the fan. I got cavity resonance with an Acou...
