Artic Cooling Silencer right blow direction?

[Ranger78]

I put on my Sapphire 9800 pro an Artic Cooling Silencer rev. 2. It's very quite and easy to install. However it seems to me that the fan does not blows air from inside the case to the outside by the rear slot, but it seems it blows air inside the case. What's wrong with that?

Hello,

I noticed on my card (ATI Silencer 5 rev2) that at the inlet (fan) it seems like it is blowing into the case on one side of the fan and that the fan sucks air on the other side of the fan. It is almost like the air is bouncing of the spinning fan on one side -> but it is not blowing hot air into the case<- so it is probably normal.

If you check the outlet it seems like the air is blowing out on one side of the opening only. The amount of air flowing through is not alot but it works well my Ati silencer is doing a great job. It lowers the gpu temp at full load by 25-30c compared Ati stock fan on my X850XT.

Thanks for your help, but my impression is that no air is blowing from the outlet in the back of the pc... well, maybe I'm wrong, so what software can I use to monitor my gpu temperature??

I'm not sure. I don't think that the 9800PRO has temperature monitoring built into it :-(

I can't believe that! :eek: :eek: Anyone else can suggest me a program to monitor my 9800 pro temperature?

there is no prog.
but its always like this it seems there is no air coming out but it cools and the 9800pro i think has no temperatur monitoring

It could be that it is in fact moving a lot of air, it's just that it is low pressure. Most fans (such as an 80mm) will move 30cfm or so, but since its 30cfm through an 80mm hole, it feels like a lot of air. In contrast, if you were to move 30cfm through say a 120mm hole, it would feel like its moving a lot less air, because its got a bigger hole to go through and therefore less pressure. Also, the fan was designed to go slow, 2,000rpm I believe. That speed on a (I think its 72mm?) fan I don't think would do much more than 18-25cfm.
