The Thermaltake TMG AT1 Heatpipe Video Card Cooler is part of Thermaltake's new Thermal Maximum Grade (TMG) series of products. Featuring unique high performance designs for various applications, the TMG series ushers in a new era of component cooling.

• Super silent at 16dBA

• Effective cooling for the GPU and video card memory at the same time.

• 2 Heatpipe for maximum heat transfer.

• 6 Year Limited Warranty

Detail Features

• Exquisite soldering heatsink made by 2 Heatpipe, large copper base and perfect ratio aluminum fin.
• Blower fan with special blade design : rotating extremely silent.
• High performance thermal grease w/ higher thermal conductivity
• Thermal Pad: Included thermal pads give good contact between BGA memory and large copper base which conduct heat quickly.

Unique Air-flow Pattern
Dual way air-intake increase air flow to achieve better cooling.

Enter Bearing
High performing Enter Bearing, decrease bearing wear Down and extends the MTBF(Mean Time Between Failures) of fan.

Extremely easy installation, uses 4 of the stock holes around the GPU and that''s it. Looks like a stock part unlike other solutions for the X1900 series. Completely silent fan, which is a real plus for replacing the stock air blower fan of a X1900XT. Cools voltage regulator heatsink by drawing air from above and below the fan. DHES, a major plus by exhausting hot air from the GPU outside the case. Dual 6mm heatpipes with a large copper base that cools the GPU and memory. Uses long, thin aluminum fins to better dissipate heat (stock X1900XT heatsink is all copper base and fins). Dropped idle temps by 14C, from 56C to 42C. Dropped load temps on Battlefield 2 from 95C max to 71C max. This is from a Florida resident. High performance with complete silence and making a part that easily blends in with stock yet also looks very good. Two thumbs up!
