Well this came as a surprise to me

I am working on making my comp quieter, so far plans are get si-120, s12 600w, and replace all fans with coolermatster 22dba fans. I have just opened my case, and stopped my cpu fan by hand and it did not change the noise at all. i made sure it spun back up or i was going to reboot and it did. I then did the same to the chipet fan and same thing no noise differnce and it spun right back up. To my surprise i now beleive the noise is coming from my GPU which it thought was quiet. For a while i have believed that the main sorce of noise was the cpu fan and it is not so i need sugestions on waht to do. Zalman 700, or artic. Any other noise reduction sugestions are welcome. Thanks for your help. Rig in the sig.
 
I discovered the same thing, too, when I replaced my case and all my fans. It came as quite a surprise.

I plan to get the Zalman VF700 AlCu and throw a very low speed 92mm fan behind my PCI slots to exhaust air from under the video card. Hopefully that will keep things cool and quiet.
 
I found the same thing. GPU cooler was the loudest fan in my computer. Changed it for a VF700CU. Cooler, quieter, even in "silent mode".
 
i cant really here the PSU or Fans, i have put my ear up to them but no where near as loud as the gpui cleaned off the the dust. which i was un aware of, from the mes aroudn the fan on the gpu. it seems the be a bit quieter but not much.
 
I've owned both VF700 and AC's NV5. 1st off though, after your gpu fan, USUALLY, but not always, the psu is the noisy culprit. That said, my take on the 2 gpu coolers and mileage will vary: VF700 on low is quieter than the AC @ stock and cools 1-2C better than the AC. At full tilt the VF700 is considerably noisier than the AC @ stock (which is full tilt) and the VF700 cools 1-2C better. The kicker for me and many others is the AC's exhaust feature. With the VF700 ALL my temps went up anywhere from 1-2C to 4-5C depending on the component. With RivaTuner (www.3dguru.com) you can controll the Silencer fans speed like SpeedFan for example. This is awesome. I run my Silencer at 34% (~700rpm) @ idle and it bumps up automatically to 100% (~2000rpm if I remember correctly) when I game or a 3D app is started. At 34% the Silencer keeps my 6800GT at 50C idle (room temps are ~72F) and is absolutely inaudible from 1 meter. Plus I house it in a P180 so its inaudible from 1 foot in my case. Both coolers are sweet pieces. The Zalman is a higher quality HSF by far, but it depends on your setup to which will benefit you the most. G-Luck 😉
 
well i was thinkingm get a zalman vf700 a panaflo on the expansion spots the putt the hot air out. im not sure yet but i will figure it out any more opinons are great
 
For 6800GT, VF700 >> NV Silencer 5 (It seems Arctic cooling did a better job for ATI than nvidia) If you want to help dissipate that hot air from the zalman, put a PCI slot cooler next to it . . . that should help a lot . . .
 
the zalman 700 is so nice I highly recommend it

It's quiet

I've seen a more consistant fps when playing first person shooters
 
I did the switch to the VF700Cu with a Zalman Fanmate so I set the fan speed exactly the way i like it. Awesome.
 
Haven't used the NV5, but one of the common complaints is that a lot of the time it doesn't match flush with the vidram and you have to either layer thermal tape or lap it.

Mainly because of that, I got the vf700 and love it. I control the fan through CoolDrive 6, but before that I was using SpeedFan.

One thing, the Zalman has a 3-pin plug so it can't be plugged into the vid card. It comes with an adapter to plug into 4-pin molex if you don't have a spare MoBo connection. NV5 plus directly into the card.

-z
 
I have the nv5 and it works perfectly on my card. I know for sure it was making contact because i removed it to reseat the cooler and it had imprints of the ram.
 
The AC has quality problems and doesn?t move enough air to make the exhaust a compelling feature.

VF-700 all the way.
 
This thread has halfway convinced me to get a VF-700, the only question now is how long would it last? I'm not quite up to date on hardware (check sig for evidence), so the next card I'd get is probably something that's out already.

The graphics card quiet coolers would most likely last longer than the usefullness of the graphics card itself.

Physically, the Zalman VF700 will last as long as the average fan which is ages. Usually something daft like 50,000 hours give or take.

Cooling capability-wise, I dont have a crystal ball but I think it will be quite a long time before there is a stock cooler thats better.

Compatibility-wise, again the crystal ball would be useful but I think the mounting holes will remain standard for a while and most cards will be able to accomodate the VF700.

Id probably say the next 2 generations will be able to take a VF700 and the VF700 will probably be able to handle it better than the stock cooler but there are hints about flip chip designs and such like. I dont know what a flip-chip is but I could guess, I dont know whether moving from now to a flip chip design would affect the VF700 from either standpoint.

PGA (Pin Grid Array) is what old CPUs (DX/2s and similar), sound card chips, south bridges and 'old' GPUs (TNT, Rage) were. The heatsink sits on the package and the heat must travel from the die, through the packaging, to the heatsink. New CPUs, GPUs and even some northbridges use FC-PGA (Flip-Chip Pin Grid Array). The 'chip' is flipped, and the die is exposed, so the heatsink sits directly on the die = better heat transfer. If you can see the die, it's flip-chip.
Pics 🙂 :
Bottom of DX/2 Notice how the die is under the chip, where the pins are.
Top of DX/2
Bottom of P3 Notice no die...
Top of P3 ...because it's been flipped to the top!

I see. Thank You.

Im assuming this wouldnt change much for the end user apart from probably lower temperatures when using the same cooling solutions.
