I'm afraid so - unless you have access to a passive heatsink which will
do the job. Some 9800 Pro ultimate models had huge fanless heatpipe
heatsinks - if you google the model you will no doubt find some to view but
they were less than successful and space hogs inside the case - taking a ram
slot out of action and often a pci slot too depending on the mobo.
For noisy heatsink/fans attached to the PCB with spring plungers you can
carefully remove it, clean it with a fine paintbrush and put a drop or two
of fine oil onto the spindle beneath the central sticker - shoild lessen the
noise. Or if that fails the fan spindle is usually held in place in the
bearing with a plastic circlip, this also can be carefully removed releasing
the whole fan/spindle assembly and exposing the topside of the bearing. High
temp grease can then be applied to all the relevant parts and then it can be
reassembled, remounted with new thermal paste or the existing paste if you
have not disturbed it and will probably run noiselessly unless the bearing
or spindle is damaged or scored. Damaged is definitely terminal and requires
a replacement fan - but a simple score on the spindle can be moved to a less
noisy position by the addition of a very thin shim beneath the circlip.
Noisy heatsink/fans which are glued to the GPU are a less attractive
proposition for lubrication.....not impossible but risky....
Running the card without the fan will lead to it's swift demise...
