Summary: This is a great fan for the price. It fixed my overheating issues instantly and I could not be happier. It is kinda' loud on the high setting, but extremely quite on low. I find on level 2 it works just fine for my needs. I would highly recommend.
Summary: I have had 2. I had one and I loved it. Got another for my other computer and it died in 3 months. The original just died after 7 years! The best thing is that it is an intake fan. Most are exhaust, which is pretty useless. It will get lots of dust on your gpu fan, but that is because it sucks in lots of cool outside air. Just blow out your case once in a while! It will drop your CPU and case temp too, because your video card's heat will not be going into case.
Summary: I desperately needed a fan to blow on a RAID card that was getting a bit warmer than I liked and I couldn't believe how long it actually took me to find a fan that pulls air into the case versus one that exhausts. So when I stumbled on this little fan I bought two, no questions asked. Thankfully they work great! The ability to shorten the fan allowed me to double stack them and and switch them to a lower, quieter speed.
Summary: It's a slot fan that TAKES IN AIR. The biggest flaw is in the marketing; it took me six months to find this product and as far a I can tell it is one-of-a-kind in function. The build quality is better than I expected. The sections are molded in such a way that they interlock and the plastic itself is fairly hard. Assuming the fan lasts a while this is well worth the price.
Summary: I got this for my first attempt at overclocking (an old p4 system just for kicks). I purchased this cooler mostly to give additional cooling to the graphics card (nvidia Fx 5200). I installed the unit right under the graphics card without much hassle and it cools down the card nicely. If you are looking for a cooler to lower the overall temperature in an older system slightly or keep an older video card cool, I would recommend the vcool.
Summary: My overclocked (626MHZ/1053MHZ Core/Memory) GTX260 reaches 75C when running in full power. After I installed the Antec Cool two slots below my video card -- with a Sound Card in between, it actually drops my GTX260 temperature a max of 5C (in high fan speed)! Quite impressive considering the setup. However, it is the 2nd LOUDEST fan when running in max speed.
Summary: My temps before the insertion of this fan were 57c idle/67c load. After insertion, with the switch set to "H" the temps were 57c idle/64c load. In order to have the fan fit with the extender tube attached, the bottom clip had to be removed -- or else it wouldn't seat properly in the case. Pity there's no proper documentation to confirm things, so you just read it here. :) The clip can be effortlessly reattached as long as you don't break it off with force.
Summary: bought one of these babies at Staples, DID lower my temp (installed it directly below my 7600 xfx oven card and lowered temp by a measly 3C...but it sure does look pretty. Might return this and buy a replacement copper fan for the card for another 10 extra bucks and 10 extra min.
Summary: My Dimension E520 case has a lot of room but this fan is just not designed well. It's to wide to fit in the PCI slot space. The fan presses up against the unused PCI Slots and doesn't fit in the screw slots to hold the hold the card in place. There is plenty of room on the other side of the fan so it's not a problems with the case. Vcool would be smart to resize the metal ends that hold the card in place. If the fan was off set more to one side it would fit no problem.
