Passive cooling for HD4870

[Dietrich]

Hello,

I was planning a new system soon to be acquired specifically for the studio. I spend very much time in my studio and as you can sit hours nothing (for example, someone is with you synth to balls) it seems useful to have a good video card so I can still game.

Now is the Power Color HD4870, stock speeds, nothing is overgeclocked.
And I want him chilling with Accelerometer S1 Rev. 2, this gives some problems in terms of heat.
Because the site Artic Cooling HD4870 supports it but I do not know or to guess. Or will I still need to take a passive HD4850 Gigabyte?

The rest of the set
Lian Li PC-8B (stock fans)
Lian Li C-02B CD / DVD Bezel
Amacrox Calmer Fanless 460 Watt 2
Asus M3A78
AMD X4 phenomene II 940 with Thermal Right Ultima-90 Cooler Master or Z-600 (I curtsy to the Thermal Right)
2x Kingston 4 GB PC 6400
Western Digital Caviar Blue 640 GB
NEC AD-7200 S-ATA
Power Color Radeon HD 4870 512 MB + Arctic Accelerometer S1 Rev. 2 Aluminum
or Gigabyte Radeon HD 4850 MC
So you get a better picture of the remaining heat that is created and the Airflow.

Accelerometer which cools probably only good enough if you Airflow in good order, if you have a fan that blows directly on, or if you have a quiet fan to move. Got a little brackish Airflow and put no fan than he will during the game I think are hot.Over the processor cooler fit a Scythe MUGEN II ? They are very quiet, only very large. That he is not passive is not very much, over 17dB, it is not.

Accelerometer That certainly gets the temperature down enough (to 50-55 stressed) but to recommend the turbo fan module, then it really 45 degrees max.

With hd4870? It's quite a hot head so stressed at 45-50 without module or fan out, I strongly / Airflow plays a major role.
