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: Bought an open-box online, received a b-new one and worked for about 1 month before the fan motor died. You have to screw it upright for stability. Worth the purchase on discount not worth it fill price. Satisfactory at best.
Pros: Good CFM., Blue LED Lights., Adjustable positioning., 3 speed setting.
Cons: Adjustable neck is flimsy., Loud on High., Died in 1 month after using it.
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: i purchased 2 spot cool fans, to aid my sli'd 560ti setup as the cards are sandwiched together and airflow to the top card is reduced. with one mounted on the side and on at the front (by power) i'm get good intake and exhaust pressure. Noticed a 10 degree difference on 560ti #1 on medium speed setting, less on #2 as it is unrestricted.
Pros: decent leds, good airflow (maxed at 3200rpms)
Cons: mount arm is perhaps an inch too short, high setting is very noticeable, low is silent but has minimal flow
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.
Excerpt: This is a great option for cooling memory or other chipsets in an open air tech station or other situation where there isn't direct airflow. The plastic feels a little flimsy but it gets the job done. It mounts using a single screw anywhere you have one so it can mount to a case or motherboard. It has 3 speeds and is quiet enough to not be noticeable.
