Hello All,

This is my first WC project and I've a question on my 9800GTX card. After installing the waterblock, it seems wasteful to me to have the card taking up 2 slots at the back. I've already ordered a single slot replacement but as per the picture, there is a black cable attached to the double-slot back plate. Does anyone know how to detach it? It seems to be glued to the back plate. Or can I simply cut it off?



Your advice is much appreciated!
 
I would not cut it off tbh. I know it's a waste of a slot, but if you ever need to RMA the videocard, they will deny your warranty due to physical modifications.

I think theres some screws on the back that attach the backplate, but I'm not sure if it's possible to remove and replace it with another..
 
if you really want to remove it, instead of cutting it off, get some solvent like paint thinner or mineral spirits and see if you can remove it that way. Put it on a Q-tip or something similar so you don't have to worry about getting it on the board.

It appears that it might be some type of temperature probe but I'm not sure about that. Hopefully someone with a little more experience will chime in soon.
 
Although I'm not certain I think that is supposed to measure the exhaust air, to determine whether or not to speed up the fan.

If you can manage to detach it, I would just leave it attached to the board and have it take the case temp. If you cut it, your card may or may not work.
 
Thanks for the replies. Here are a couple more pictures. It seems to me that it is a fiber optic cable that transmit the "light" from a tiny LED on the circuit board to the back plate. On the back plate, it lights up green normally when I power up the machine (before I tore it apart and installed the water loop). I think I might try the remove the glue idea...

As for the warranty and RMA, I think I've already thrown it out the window the moment I removed the stock HS and fan from the board... but that's what we modders love to do, right?




 
If its an evga or xfx card they allow you to change coolers without voiding the warranty. But cutting a piece of would probably void it.
 
OK, I did it... detached the black cable from the back plate and indeed it is an optical cable that transmit the LED... see pic below:

 
Did you replace the back plate so it doesn't take up two slots?
