effective, cheap, but could be better

G. B., Amazon

  • Summary: it is an interesting design. will work on most boards and most setups (may have problems when used with huge CPU heatsinks). my low end gforce7300 never past 60C without any fan. the heatpipes are way taller than they need to be for my almost half-height board... the top radiator barely fitted my custom case... turned out to be nice as it transfer heat to the steel case and help with cooling very nicely. But if it was 1mm taller, i'd be in trouble.

Fan-less cooling for reasonable pricing.

  • Summary: The Good: If you have a PC and have need of a noiseless GPU cooler, you can't go wrong with this. Easy assembly to most modern video cards. No parts or adapters to fumble with. Brings down GPU temperature (for me) an by about 20 degrees centigrade. The bad. The cooling blades require a great deal of space. If you PC is limited in space, you're out of luck. The cooling blades attached to a GPU will mean that some PCI slots will be inaccessible.

Nice quiet but had to modify little

  • Summary: The heat sink is not fitted perfectly but was able to manage to drill two more holes for the supporting screws. After all, it's working perfectly and no noise for a 1 Gig mem nvidia video card.

Impressive cooling, poor fit

T. Qian, Amazon
7 October 2013
  • Summary: The cooling efficiency of this gigantic heatsink, when it fits the card you are installing it on, is very impressive. WIthout a fan, it brought down the temperature of my 6570 to below 40C at idle, and below 45C on load. That being said, it has several fitment problems: 1) It did not fit any reasonably new NVidia card (for example, Quadro 600).

GPU temps cut in half !!!

Matthew, Amazon
2 October 2013
  • Summary: This thing is da bomb !!! My stock cooler, on my 9800GT, was just not cutting it. Playing BF3 temps ran around 95C average, hitting 100C+ during heavy demand. Slapped this baby on, temps now run UNDER 50C. With this addition, I can now safely overclock my card :). I did not fit the 80mm fan. Although, I do have a 120mm fan right next to my G-card, but the 120mm fan was in place before installation of this cooler. For under $7, this is one heck of a deal.

Works with 53mm spaced mounting holes

Dan The Man, Amazon
16 August 2013
  • Summary: I was able to easily mount this cooler on a H.I.S. HD4830. This card has 53mm mounting holes as do the following ATI cards: Radeon HD 5870/5850/4870/4860/4850/4830/4750/4670/4650/3870/3850/3690/3650/3450. Not sure if I was just lucky but assuming your card was built to the ATI reference specification it should work. Replaced the noisy stock cooler and my idle temps dropped to 38C .

Card still HOT HOT

CA, Amazon
26 May 2013
  • Summary: even with the "fan option" installed, the gpu still runs very hot. I expected more than a 2 degree drop in temp by adding this cooler.. over-all pretty disappointed. it did fit easily and install was simple, just did not see the performance I was expecting.

Very good cooling solution for modest VGA cards

kurtgo "kurtgo", Amazon
10 May 2013
  • Summary: I had no trouble installing the heat sync. the thermal goo was a bit cheap (clumpy and didn't stick well). I mounted close to my CPU fan so it would do the work of cooling the CPU and the VGA at the same time. Overall a good solution if you have the room in your case. I took off one star for crappy thermal goo.
