Remember how much fun the original Thermoengine was? Remember how much fun the original Thermal Integration TI-V77L was? Double that and then add in a 25mm thick 5000RPM fan and you have the TI-V77N - which draws so much current TI have set it up to connect via a Molex pass thru.

If you look at the picture below of this nifty little unlabeled fan you will also notice it is upside down. The impeller supports are on top, making it look as though the fan is exhausting air up and away from the heatsink. Well, that is not what it is doing. Rather, the blades on the impeller are backwards and the fan is actually sucking in air and blowing it out the bottom.... where it would seem to normally intake air.

If you're confused don't worry, so are we. Why is the fan backwards, but blowing in the right direction? Honestly I have no idea, but I suppose someone must have figured out that the fan can draw in larger volumes of air, or produce less noise, or something else. If you know for certain feel free to tell us.

The TI-V77N uses the same heatsink as that of the TI-V77L which first made the rounds some months ago. The only difference between the two is the fan. For most of use, a smaller and quieter fan is more of an asset than a noiser fan which improves cooling factors.

Thanks to the performance freaks and cooling junkies, a noisy fan like this will produce some really good cooling results when used on an AthlonXP or other socketed processor. In general, heatsinks with this type of design have better thermal results because all the exhaust air is blown down, directly at the heat source. Other types of heatsinks simply blow this air out to the sides and it really isn't used as effectively that way.
