I put various heatsinks on them. I have some copper swiftechs and some generics from JabTech. Seems to work well... I tried small copper heatsinks attached with thermal tape (like the one inside the CPU HSF frame in this shot ) and saw no difference. The substantial improvement from heatsinks came ...

I connected the Noctua 1200 fan to my Gigabyte GA-K8NF-9-RH motherboard's CPU fan header, which has automatic fan speed control based on CPU temperature, through a Fanmate 2. If I set the fan speed controller to Disabled in the BIOS then I can control the speed of the fan with the Fanmate 2 but if ...

Also - just because a cpu heatsink fan is blowing downwards doesn't mean the air is hitting the right places, hence the positioning aspects of the thingamajug. The VRM MOSFET's on my Socket 478 Abit AI7 indicate temperatures higher then the (3.0C Northwoods) CPU under load. They were even worse for...

Swapping to a Yate Loon fan and isolating it on my CNPS 7000B-Cu made a noticeable difference in noise, and also increased the temps a few degrees.

Switching to an XP-120 and Papst fan, however, dropped both noise and temps substantially.

I'd think that pieces of bike tube would work fine as fan vibration dampers - probably better attached to the fan corners with a little glue before clipping it on the XP. The fin area of my XP-120 has never been noticeably warm to the touch, even when the CPU temp is indicated as 47-50C.
