Check this review of the TMD fams... very interesting concept for cooling solutions.

Good concept. It works exactly the same as on other motors, just with the electromagnets on the outside and the regular magnets on the inside.

Instead of wasting space that could be used for air movement, use the unused space. I like it.

The concept of TMD fans is great...but what I want to know is, can you get a higher CFM rate and a lower decible rate for some good...quiet...cooling?????

By far, the best way to increase air flow, yet reduce noise is to increase the size of the fan. This is because at a given volume of air being moved, the smaller the area it is in, the more pressure which then results in vibration as it pressure drops again, which we then hear as noise. So, when you increase the size of the fan, it will tend to move some more air, yet cause a lower pressure immediately by the blades.

Yea...that's what I have heard. Do you know if using a 60mm - 80mm fan adapter is a good way to go...to increase the size of your fan, giving you more air flow, and yet reducing the fan noise??? If so, which type of fan adapter would you recommend?

Well, fan adapters give you one or the other. If you are running a low performance fan, the noise won't increase, but it will push out more air; if you are running a high performance fan, the noise will decrease, but it will put out as much air. This is because you are running a given amount of air through the smaller hole size, except it is eased into the increased pressure (vs. larger hole). I would just suggest getting out the Dremel and increasing the hole. Heck, just put a window in while your at it.

Do you have an AMD CPU? 50C is the minimum stable tempeture, anything over that and you can expect problems :/
