Top performing socket A/370 heatsink — Joe
SUMMARY: Exceptional performance, secure socket A mounting, but noisy with the 80mm Delta 68 cfm fan.
looks very nice – polished finish and flat. It is a tad better than the prototype I tested. Thermalright includes four screws for a 38 mm fan; the fan is set off the base four rubber washers (5mm) – it decreases noise a bit and may reduce vibration also.
I measured noise with a Radio Shack sound meter 8″ from the fan’s intake at 68 dBA – about the same as the Delta 60mm 38 cfm.
The AX-7 was tested on the CPU Die Simulator which gives results that are unaffected by motherboard influences.
For this test, I used the Delta 68 cfm (FFB0812SHE) fan.
|Simulator, 76.7 Watts, Delta 80mm|
The Die Simulator indicates this is a top rate heatsink. These results place the AX-7 at the top of heatsinks we have tested (Heatsink Rankings HERE). Note that air cooled heatsinks are approaching water cooling C/Ws, although at much higher noise levels.
The AX-7 is top rank with the noisy Delta 80mm fan. Performance will scale based on which fan is used.
Thanks again to Thermalright for sending the AX-7 our way – an great design.
