We firstly tested with the reference ASUS cooler installed on the GTX690, recording the results to use as an all important baseline. The card was then disassembled and the ARCTIC Accelero Twin Turbo 690 Cooler installed. The room environment was maintained at 24c throughout all the tests.
Firstly we checked temperatures after booting the system and letting it idle at the desktop for 15 minutes.
When idle, the ARCTIC Accelero Twin Turbo 690 Cooler improves on the reference ASUS cooling solution by 7c, dropping the temperatures from 31c to 24c.
Next, we test with Furmark, using the intensive stress test for a solid 15 minutes, then taking a snapshot of the results.
For ‘real world’ gaming results, we let the card idle for 15 minutes then play Max Payne 3 for an hour, recording the maximum temperature during the playing session.
There is a substantial improvement after installing the ARCTIC Accelero Twin Turbo 690 Cooler. Load temperatures when gaming drop from 74c to 61c, a fantastic result for the GTX690.
The Asus GTX690 cooler performs well, dropping temperatures from 81c to 60c in 12 seconds. After this the fan spins down considerably to reduce noise and it takes a full 2 minutes to return to idle.
The ARCTIC Accelero Twin Turbo 690 Cooler by comparison reduces temperatures from 69c to 40c in 7 seconds and then to 24c in 17 seconds. The 10 heatpipes and dual fan configuration are able to disperse the heat much quicker.
The ARCTIC Accelero Twin Turbo 690 Cooler fans spin at 30% when idle, translating to around 870 rpm. When gaming, the fans spin to 1,000 rpm, generating 32.2 dBa noise. In Furmark, they increase speed further, to 1,200 rpm which generates 33.1 dBa noise. Still very quiet.
The ASUS GTX690 cooler fan spins at 1,150 rpm when idle (30%). This rises to 1,900 rpm when gaming, generating 35.4 dBa noise. When stressed in Furmark, the fan spins higher to 2,000 rpm (60%). Noise increases to just under 36 dBa. This is also a really good result for a ‘reference' cooler.
