Accellero S1 Cooling Performance Review

post #1 of 3
Thread Starter 
I recently purchased the Arctic Accellero S1 rev.2 GPU cooler for my Nvidia 9800 GT, and here is some uplifting cooling #s

Software used - Kombustor GPU Burn-in D3D 10
Ambient temp - 23C

Stock cooling:
The gpu climbed over 100C within 10 minutes and had to end the burn-in before exceeding 105C as I don't want to fry my card even if it is old. The fan was running at 100% set manually with the shroud. Without the shroud and a 120mm fan cooling it from the side panel it exceeded 100C slower, but still had to end the test before exceeding 105C

Accellero cooling, no fan:
The gpu climbed to 93 and stayed put, a very acceptable temperature for 100% load on the card with 0 noise. All that heat is being vented into the case, but it was with the stock cooling on this card regardless. That's 12C cooler and 100% quieter.

Accellero cooling, 120mm remote fan:
For this I used a Thermaltake TT-1225 fan about 4 inches below the card to assist cooling. It climbed from an idle 39C to a load of 43C after about 30 seconds and stayed there for about 15 minutes until the AC kicked on, and the cool air from the AC dropped the load temp to 41C (the AC duct is approx 11 feet from the intake cooling the card on the ceiling, the fan is blowing from the floor up into the Accellero). I stopped the test at this point as it was obvious the temps were not going to climb over 43C.

Overall, I would say for the price, this is one of the best cooling solutions for a high-temp graphics card. I would definitely suggest having some kind of direct airflow onto the Accellero, whether it be their turbo model or a setup like mine, having a 120mm fan blowing air from a vent in the bottom of the case, but even without a fan, the Accellero is probably the best silent option if you have the room (6" from the motherboard to the side-panel or side-mounted fan and 8 1/2" video card clearance, it sits about 1 1/2" away from the video card as well).

Installation was relatively simple. The product I received had thermal paste pre-applied, and it was just a matter of disconnecting the stock fan and unscrewing the stock heatsink. Make sure to use rubbing alcohol or a similar product to COMPLETELY remove the microscopic residue from the GPU (I used Denatured alcohol, and apparently it worked brilliantly).

One negative thing to say about this product: The RAM heatsink tape is weak. Use an eraser to clean the RAM on the card before applying the heatsinks. Also, be sure to check that the heat pipes are not going to dislodge a heatsink, that was a rather annoying situation I got myself in there as I had no spare thermal paste.

Sorry for the rather amateur review, it is my first review on a PC product. I hope it helped those out that are unsure about GPU cooling like I was.

Nicely done, although you shouldnt run it without a fan.

The Accellero is designed fanless, it uses an enormous aluminum fin system with 4 direct contact copper heat pipes to dissipate heat, the fans are strictly optional, but with a hotter/higher end graphics card fan(s) are recommended.
