Need replacement FAN for ATI Radeon HD2600Pro graphics card. Where are best sources?

Some ideas,

Skipped past the ATI Radein HD2600 Pro, (More of an Nvidia fan), so I don't know how they have the fan/heatsink attached.
Don't know if they used Thermal Glue, or Thermal Paste for the heatsink. (Or a thermal pad)

It is Always best to replace the thermal compound. Cheap insurance.

A) Thermal Pad:
Remove the heatsink.
Carefully remove the pad the best you can, then use Q-tips dipped in Isopropyl Alcohol to soften the remnants. Follow with a plastic scraper, (Old credit card?), and more Q-tips dipped in alcohol.

Make SURE the top of the GPU is CLEAN. Then properly apply fresh thermal paste to the top of the GPU, and set the fan/heatsink assembly in place. Lock the fan/heatsink assembly down.

[ GPU
Graphics Processing Unit,

http://en.wikipedia.org/wiki/GPU

The GPU used in an ATI Radeon HD2600 Pro graphics card, is an ATI RV630,

B) Thermal Glue:
Requires using a hairdryer set to low heat, and constantly moving the hairdryer's nozzle around slowly.
Once the glue softens gently twist the heatsink loose.
(Wear gloves)

C) Thermal Paste:
Remove the heatsink.
Use a clean plastic scraper, and plenty of Q-tips dipped in alcohol on the GPU.

(Isopropyl Alcohol. Commonly referred to as Rubbing Alcohol.
91 percent is best, 70 percent will do in a pinch. Advise against 50 percent.
50 percent alcohol, 50 percent water.

CAUTION!!
Isopropyl Alcohol is EXTREMELY FLAMAMABLE.
Use in a Well ventilated area with NO sparks or flames present.

Once you set the heatsink, or fan/heatsink assembly in place, and have it secured, look at a side view of the graphics card.
Room well lit, and a light background.

See if the heatsink is sitting flat. You do not want it sitting at a slight tilt.

As you can see, I am trying to steer you towards making sure the thermal compound, is in good shape. It is best to just replace it. Thermal paste is cheap stuff.

For additional questions post in a Comment.

{To Add:

Heatsink:
Basic construction is a plate of metal with tall, thin fins protruding from it.
The plate of metal absorbs heat from whatever object it is placed against, (In this case a GPU)
The tall, thin fins absorb heat from the plate.

The fins then radiate the heat away.
With a fan used in conjunction with a Heatsink, the air flow from the fan helps carry heat away.

Thermal Compound:
{Thermal Paste, Thermal Glue}

The top of a Processor, and the top of a GPU are not perfectly smooth.
A magnified view would detail, 'Hills, Valleys, and Pitholes'

Same with the bottom of a Heatsink. (The plate)
When the Heatsink is set on top of the Processor, or GPU, there are air pockets created from the imperfections of the two surfaces.
Air is trapped in-between the two surfaces.

{Heatsink on top of Processor, or Heatsink on top of GPU}

Air is an Insulator. Not a Conductor.

Thermal paste fills the voids, (Imperfections), and is an Excellent conductor of heat.
Thermal paste, (or a Thermal Pad), can dry up over time.
The thermal conductive properties are gone, or negligible ]
