NV5 Silencer question

See, I wasn't getting any decreases with mine, either, but I'd only mildly tightened the screws to where the rubber washers were in their normal shape. I've now tightened them to the point that they're about half the size (squished), thus applying more pressure to the GPU and the RAM. I'm going to toss the card back in (been running the XT PE for a bit to play around with), and see if the temps are any different now. I had a high profile fan on my GT previously, and that was doing just fine (and without a noise difference, I might add), so *shrugs*

Hopefully tightening the screws makes a difference.
 
My fan also seems to be blowing air "in" instead of out. However, I used arctic silver 5 on mine and tighten the screws alot. My idle temps are 55 C and full load is 68 C.
 
Idle temps are about 42C, load is 50C (small difference with tightening the screws, but not much). Meant to add that I'm running 440 Core/580 mem right now in testing those temps.

Guys, I understand that it is "advertised" to exhaust hot air. But if that fan in my posted pic is turning counter-clockwise, its pulling air in, not pushing it out. Look carefully at the blades and the overall position of the fan. It's either that or very poorly designed. And I can say that because I design cooling solutions for medical equipement. And just by looking at this NV5 cooler, its just wrong. Then again, I don't have one in my possesion so, just my observation. We call that kind of fan a "squirrel cage", or "blower".

Test one with an anemometer and write a scathing technical review that shakes the pc world to its core :Q

What's up with you? Are you mocking me? 😛

No, I am serious. If I had access to and was familiar with the proper operating procedures of an anemometer I would do it myself.
 
Don't hold your hand near the fan inside the case in order to figure out the direction of air. There is too much turbulance and you will not be able to figure out what is going on!
Close the case and hold a small piece of kleenex at the back near the silencer exhaust. You will see that air is coming out.

If your temperature is too high, inspect the heat sink and look for components on the card that are in the way, like large capacitors or DVI or VGA connectors in the back. You may need a dremel to work on the heat sink to make the heat sink properly seated on the GPU.
 
u should of bought a leadtek card ..... 54 degrees idle at 401/1.1ghz, and its not noisy (at least to me) at all, an i love the shiny copper!!!
 
my silencer pulls air in from the case, and pushes it out the back. a slight turbulance can be felt near the fan intake (tho that's normal with any kind of fan), and i can definately feel hot air at the exh. port. the fan rotates clockwise.

as for your temperature compared to other people's, it's absolutely irrelevant. the only relevant comparisons would be before and after in your own system (tho even then that's not entirely accurate depending on the ambient room temp), as there are multiple variables which would invalidate your results compared to whatever someone else posted.

i had issues with my stock gt hsf, but the silencer has remedied those, with my load temps over 20c lower with the silencer; i'm quite happy with it.

the gt runs 410/1.1 and my idle temp is 56c, and full load is about 70c with the silencer, but again, you can't really compare my temps to yours, as the conditions inside and outside my pc is quite different from yours i'm sure.

Thanks Navid, it seems that my Silencer is pulling air out.

true, and for sound it performs admirably ... but the unimpressive cooling and the fact that it doesn't perform as advertised re/airflow cancel that out and then some.

Did you actually test to see if air is exiting out the back as others have suggested? The poster above you thought he had the same problem you describe, but doesn't.

good point, the fan positioning is kind of funky, and of course the case was opened so not representive of how it would operate once the case was closed. i may try your suggestion before shipping it back.
 
I bought the NV5 and installed it yesterday. I used Arctic Silver compound instead of the stuff they give you in the box. I was expecting a dramatic difference but was dissapointed by my results, only a couple degrees cooler than my stock BFG cooling unit. I was able to increase my overclock by 5mhz from 406 to 411 whoopee. I thought the same thing as Joecool that the airflow was reversed somehow and that I had a faulty unit. Well this proves that I was wrong

The funny thing is if you take the thing in your hand and spin the fan clockwise with your finger, air blows out forcefully from the fan and you cant feel anything at the exhaust port. If you spin it counterclockwise you feel a breeze at the exhaust port. Isn't this the opposite of what the design says it is supposed to do?
