Worse Performance From A Vga Silencer?


Recommended Posts

Yeah, like the title says, I tried a VGA silencer and I'm not too impressed with it. After a few minutes of 2D (ie desktop stuff) it completely froze. I hit the switch on the back of the PSU and opened the case up. I couldn't touch the back of my video card over the RAM for more than a couple of seconds, and no, I didn't have it overclocked at all. I do have ramsinks, but with no airflow over them I guess they don't do much.

 

Has anybody else had problems like this with a VGA silencer?

The idea is that it will cool down the heatsink itself... The air from it will be pushed directly onto the heatsink and cool off the whole area the VGA Silencer covers (assuming you put the Silencer on correctly :P). Any area not being cooled by the dual PCI fan (though it shouldn't happen) will spread the load of heat onto the rest of the heatsink anyway so there shouldn't be much to worry about ;)

But a VGA silencer contacts only the GPU, and covers the ramsinks. I don't quite get how a fan card below the silencer will get to the ramsinks.

 

Maybe I'm just having a dumb day?

Lol, I understand your concern Some Guy... The basic idea I'm getting at is that by lowering the temps on the underside of the card, you'll be letting the upper side of the card distribute heat a little better... If you want to cool HARDCORE!, you could always duct one of those two fans right on top of the ram. :P What type of thermal contact adhesive did you use?

 

P.S.

On a seperate note, I think my vid card is having issues as well, to bad no one replied to my thread in the gaming section :(

To me it sounds like you have some contact problems. Have you checked you got a good contact between the vga silencer and the core on your gfx card? And what kind of thermal interface material did you use?

 

I know that installing it will reduce the airflow over your ramsinks on the card, but it shouldn't be enought to make the card freeze up. In my opinion, unless you're OCing then ramsinks don't actually do that mauch anyway.

I used ceramique originally... should have known better - the GPU core is slightly concave, so the ceramique was too thick in the center I guess. The silicon goop they provide is making it work better, but I'm still not totally impressed with this thing. I think I might exchange it for another one, because this one's been installed before I got it (I had to clean goop off of it before I installed it), so maybe there was a reason this particular one was returned before. Maybe the fan's not running as fast as it should or something.

That sounds fishy..

 

Mine installed without a hitch, and allowed me to OC to new levels. Definately worth it. :)

Yes I just installed the Silencer like a week ago and have heard and have nothing but great things about this cooler.. check out the reviews. I seriously doubt RAM cooling is an issue, especially in 2D!

 

Definitely sounds like a GPU cooling issue. Can you see the fan working? Can you feel the air blowing from the exhaust PCI slot?

 

I had to install the Silencer several times to get it flush and tight on my GPU... forcing it into it's PCI slot and fastening it made it lopsided. I could physically see that I didn't have full contact, it was on at an angle. So, before you turn your system on, make sure that you check it from all angles to make sure it's on tight, and more importantly, even. Then check to make sure your fan is working by feeling the exhaust.
