Summary: Purchased to cool the Vram on the back of my msi gtx 680 4gb twin frozr. Does whats its suppose to do and quite effectively. They were a bit load but I have the going through my fan controller so no problem.
Pros: Adjustable., Good sized fans., No clips just attach to your B screw holes
Summary: I bought the first one, but it was defective: this cooler has 3 speeds - low, medium and high. Well, the first that I received did not have the low speed. Ncix.com technical support was very nice, they replaced me very fast the defective item. I just installed on my PC the second one, but like I sad before do not expect that it will cool very much your system. However, I plugged in my PC to refresh a little my hard drive.
Summary: The term spot cooling applies rather well. Applied this onto a motherboard to blow air over a passive GPU. WIth the right angle it blows air over the chipset & even the ram heatsinks too. Since the device pivots it grants pinpoint accuracy. THe blue led is a nice touch. This is a must have for any build. The cheapness on the stalk is the only negative. Once set, it tends to droop an inch or two when you let go.
Summary: I installed it right between my cpu heatsink and the graphic card. It help the flow within the case. It cooled my cpu lowering it by 2 degrees and my graphic card by 5 degrees. The LED can be annoying if u have a different LED color on your other fans. It took me some time to install it since I had to find an extension to the cable.
Pros: Flexible, good airflow, speed adjustable to your needs,
Summary: Mounted on my motherboard to provide additional cooling to the back of my 6970 video card. The three speed fan switch is nice to reduce fan speed and noise. I prefer low noise so I keep it set on the lowest setting. At this setting the fan can not be heard over the case fans.
Pros: Provides a good spot cooling solution
Cons: Adjustable plastic head mounting a little flimsy but it works
Summary: I've got a dual video card setup so I figured they could use more cooling. The stem not being as long as I'd like, I found to be a bit tricky to get in the right spot. I did eventually and it's been working good.
Summary: For anybody that's wondering, the fan is ~80mm and with the frame, ~90mm. Not exactly small but not impossibly huge either. But at that size it gives a good balance of static pressure and versatility with a minimal dead zone behind the fan hub. The fan hub is see through, and looking at the design, it doesn't look like a ball bearing fan, but it sure sounds like one. It's quiet enough on low, but the bearing makes a lot of noise.
Pros: relatively quiet on low, good airflow on high
Cons: a little bit big, bearing noise, bright LEDs
