X800 in a SFF

I was just curious if anyone has an X800 in a SFF case. I was thinking about getting one but i always figured heat would be a major issue with that card in such a small case. Can anyone shed some light on this?
 
I'm running a fairly highly overclocked X800 in my current SFF box, and it worked in my old SS51G (only 200w psu) before it. So yea, you'll have no problems.
 
If heat becomes an issue you can always do the mesh mod to the side of the case

Yeah, don't buy the one Shuttle produces as its meshed on both sides and will cause the PSU to increase in temp rather than decrease. I believe this is due to the way Shuttle vents the heat from the PSU and uses the internal air pressure in the box. Just mod your own by buying a mesh garbage can from Target for $8 and do it yourself.

When you DIY, do you mesh both sides. Wont that have the same effect as the one that Shuttle produces.
 
My x800 Pro (running at XT-PE speeds) runs excellently in my meshed Shuttle. Do yourself a favor and go for it.

so is it good or bad to have mesh panels on both sides? I'm going to do mesh but after reading this I'm not sure if I want to do one side or both. I took the cover off after some use the other day and the PSU casing was hot as hell, my thinking was that if mesh was there the heat could dissipate, but if the fans work with some kind of internal pressure of the case....
It does not make too much sense about the pressure part though, if you do one side of mesh you've totally changed the pressure and airflow of the case, in theory more air flow and air contact should be best for heat dissipation, unless my logic is flawed.
What do you guys think?
 
I don't think presure is a thing to worry about. We're only talking about a small amount of air in that case. You would need some big fans to build up presure like that.

Someone correct me if I'm wrong since I don't have a SFF
 
Well, with 2 x 10k RPM drives, a DVD Burner, 3.6 GHz processor, and the overclocked x800 my system still runs pretty damned chilly with the premeshed (both sides) cover.
CPU: 39c - 53c
System: 41c - 44c

My wife has a sealed SB65G2 with a 2.6 GHz with 9600 pro and single 250 GB drive.
CPU: 38c - 54c.
System: 40c - 42c

I taped over one side and saw no difference.
 
The difference can be blamed on both your ambient temperature in your house as well as which model of PSU you are running. Since I am currently running a v1 of the SN85G4, the PSU runs toasty in this box so much that if I place my fingers on the side of the PSU after an hour of use it will burn my fingers. The v2 model fixes these issues. The mesh on the V1 raised the VRU units under the PSU (measuring with SpeedFan) +7c. In comparision, running with my stock shell it ran at acceptable levels. Covering the PSU side of the box helped the VRU measurment by 4c, but still not the same as the non meshed case shell. Another thing to take into account is that there is a PSU fan next to the ice fan (60mm) that takes the air and forces it out the back. Other designs of the Shuttle XPC's don't use this design (next to the CPU socket). Hence why I cannot upgrade the PSU with the newer SilentX 250watt PSU from Shuttle. It's one of the few models that this new PSU won't work in.

It is quite possible that the Intel box will run with the same mesh grill fine, but again you must take into account for ambient room temps. Here in CA, my house hovers around 80F during the day and there is no humidity in the air. It is possible to have the same setup running in an Air Conditioned room running quite well vs. a non AC household.
