NV Silencer 5 installation for the BFG 6800 GT OC with 2-fan cooler
General comments: This is a step-by-step guide to installing the NV Silencer 5 on a BFG 6800 GT OC. It is meant to be very simple. It is a supplement to the instructions provided with the NV Silencer 5.
To do this installation, you will need:
BFG 6800 GT OC graphics card
NV Silencer 5 heat sink-fan
Arctic Silver 5 (AS5) thermal compound (the itty-bitty $9.99 tube is plenty)
An open PCI slot next to your graphics card
A clean, flat surface to work on
A Philips screwdriver
Isopropyl alcohol (90%+) [also known as: ordinary rubbing alcohol]
A lint-free cloth
A small, clean plastic baggie
*NOTE*
Modifying or overclocking your graphics card will void the warranty. And while I explain how to reverse the process, I do not encourage or condone fraudulent warranty claims against BFG or anybody else.
*CAUTION*
This process is pretty simple, but careless handling of your graphics card can result in impaired function or total destruction. Be careful and work slowly.
*CAUTION*
Beware of static electricity. Periodically touch the grounded frame of your computer to prevent zapping your card or destroying other computer hardware by accident. Also, dont scuff your feet on the carpet or comb your hair during this procedure. This will not be a problem as long as you exercise due care.
I. Baseline Information
Before you install the new cooler, turn on your PC. We need to find out what temperatures your card runs at with the stock cooler to know if the NV Silencer 5 is working properly after you install it.
Right click on your desktop, select nVidia analog [or digital] display. This will bring up the nVidia control panel, then one of the options you can select is to view the temperature the card is running at.
Record the Core and Ambient temperatures you get when you turn on the computer. Move the temperature display to a corner of your desktop.
Next, download RTHDRIBL:
http://www.daionet.gr.jp/~masa/rthdribl/
Install it, and run it in a window. Move the window & stretch it as big as you can, while still being able to read your temperature display. Turn up the Multisamples setting in RTHDRIBL setting until your FPS drops to 25-35. Let it run for an hour and record the Core and Ambient temperatures while RTHDRIBL is still running. Then close RTHDRIBL, wait 15 minutes, and record the Core and Ambient temperatures.
At this point you should have recorded the following temperatures:
Core & ambient temperature when you turn on the PC
Core & ambient temperature while running RTHDRIBL
Core & ambient temperature 15 minutes after running RTHDRIBL
II. Installation
To begin, unplug your PC. Open the case of your PC and touch the metal frame to get rid of any static electricity on you. Remove the power connector from the BFG 6800 GT OC, unscrew the screw attaching the card to the PCs frame, and remove the card. Dont forget that with AGP cards you often have that little tab you have to push in at the end of the slot to unlock the card. If you force the card out of the slot, you may break it.
Next, take the card to a clean work area and set it down. Next, you need to remove the old heat sink/fan on the front of the card. This is actually very simple. On the back of the card is a black x-shaped bracket held on with 4 screws. These are those weird screws that are easily removed with either a Philips or a standard screwdriver. Unscrew them, set them aside, and take off the bracket. Unplug the fan from the card.
You should be able to pull off the heat sink/fan with minimal effort. It is NOT glued on, but there is a layer of white thermal paste between the chips and the bottom of the heat sink that may cause it to stick a bit. All you should have to do is to slowly, gently pull the board off the heat sink/fan. Dont just yank it off hard or you could break something.
At this point, look at the board. You should see this nasty white goop on the GPU (the big middle chip) and the RAM (the other chips around the GPU). Luckily, this is pretty easy to clean off; isopropyl alcohol dissolves it easily. Use it with the lint-free cloth to clean everything off. The isopropyl alcohol is harmless stuff, so dont worry about getting some on the board. Just dont dunk the whole card in a bowl of it or something.
Next, follow the instructions in the link below for applying the AS5 thermal compound. You could use the thermal goop that comes with the NV Silencer 5, but the AS5 is generally considered to be a better thermal conductor. This is where the little plastic baggie comes into play, by the way.
http://www.arcticsilver.com/arctic_silver_instructions.htm
Some things to be aware of:
The AS5 is stringy, nasty, goopy stuff. Apply it in small amounts at a time. Just apply it to the RAM chips and the GPU.
Dont worry if you get some on the card. You can clean it off with isopropyl alcohol and a lint-free cloth. AS5 isnt an electrical conductor, but you still dont want to leave blobs of it on your card.
You may need to use more on the RAM chips to get good contact with the Silencer.
Yes, one of those tiny $9.99 tubes of AS5 is plenty.
Follow the instructions for washing it off in the link above. You dont want to leave silver particulate goop all over you.
Once the AS5 is on the RAM and GPU, install the NV Silencer 5. It should slide right on, just like the old heat sink/fan did. Then use the screws and rubber washers that came with the Silencer to screw it on. Key things to remember:
The rubber washers go on the backside of the card. Otherwise, the Silencer wont make contact with the GPU and RAM that it is supposed to cool. The crappy instructions that come with the NV Silencer 5 illustrate the right way to do this.
Do NOT screw it on too tightly. Otherwise, the screws or even the board could break. Gradually tighten the screws until there is good contact between the Silencer and all the chips it is supposed to cool.
When in doubt, use more AS5 instead of risking over-tightening the screws. Generally the RAM needs a little more AS5 than the core.
There is a little bit of a balancing act here, since you want to use the minimum AS5 you can, but you want to make sure you have 100% contact. Hold the assembled card up to a bright light and look at it edge-on to make sure you are getting good contact on all the chips. You may want to *GENTLY* squeeze the Silencer against the board a couple of times to make sure the AS5 is properly set.
Finally, plug the little power cord for the NV Silencer 5s fan into the card.
Re-installing the card is the same as removing it, but in reverse. The only thing to be careful of here is that the Silencer makes the card a lot bulkier, so you need to be more careful not to bang it into anything when putting it back in the AGP slot. Dont forget to plug the power connector back into the card. Also, you will want to remove the metal bracket thing at the back of the PCI slot that the Silencer is taking up, so it can vent air out of the case like it was designed to.
Now close up your case, plug everything in, turn on your PC and see if it works. We arent done yet, however.
III. Testing the Silencer
Repeat the steps listed under Baseline Information, recording the new temperatures you are getting with the NV Silencer 5. Your idle temperatures (before & after running RTHDRIBL) will be a couple of degrees lower than stock. The key, however, is the core temperature under load. This should be about 10C cooler than the core temperature under load with the stock cooler. If it isnt, you may need to re-seat the Silencer, or add a little more AS5, to make sure you are getting full contact between it and the GPU and RAM chips.
At this point you should have recorded:
Core & ambient temperature when you turn on the PC
Core & ambient temperature while running RTHDRIBL
Core & ambient temperature 15 minutes after running RTHDRIBL
Note that the AS5 with set after a certain number of hot/cold cycles, and will conduct heat better than after you first apply it. This will be worth about 1-2C cooler temperatures.
IV. Re-installing the old heat sink-fan
The stock HSF is inferior to the NV Silencer 5 in every respect, except that it looks cooler and is smaller. Should you want to re-install the old HSF, you can do so easily as long as you kept all the old parts, including the screws. You can even remove the AS5 and replace it with white thermal paste like BFG used if you wish. Thus, the NV Silencer 5 installation is 100% reversible in all respects.
V. Overclocking
With better cooling, you can easily overclock the BFG 6800 GT OC to Ultra speeds and beyond. The simplest way is to download Coolbits 2.0 and install it, this will unlock a variety of options in the nVidia control panel, to include overclocking. However, you overclock at your own risk, and doing so will void your warranty. Also bear in mind that heat isnt the only problem associated with overclocking; at high clock speeds, your 6800 GT may simply draw too much power for your PCs power supply to handle, making your system as a whole unstable. Also, because GTs run at 1.3 volts (vs. 1.4 volts for an Ultra), your maximum overclocked clock speed may not be as high as an Ultra, unless you modify the video cards BIOS to increase the voltage, which can be risky.
