R5x heatsink with GPU aka long heatsink FRU: 91P8756 heatsink, used in both R51 and R52; all with GPU.

I can supply you with a nice 15" R52 with XGA, which has the following mods:
T43 motherboard with X300, M750 CPU (1.86GHz), long fan for T43 ATI, 2GB RAM and HEY, a SATA-mod!!!
It also includes a good DVD/CDRW drive, no HD, but HD cover and caddy are included.
It doesn't have 1394 Firewire.
All in great condition.
Shipping to Canada is $45.95 (blame USPS

)
PM me if interested.

Funny thing, already have fully upgraded R52 but no SATA mod, must have is long fan heatsink used in GPU equipped in both R51 and R52. This way anyone can respond and sell easier without taking apart to get needed parts.
I do not need working thinkpad again, prefer not working or stripped down but still have heatsink.

This is easy to tell, look in the heatsink grill outlet; where copper plate goes across, there is a gap on top between plate and thick copper. The other non-GPU R5x heatsinks have no gap in that spot.
Created two photos to help you to identify in R5x series of non long and long heatsinks:

All R5x long heatsinks (for GPU), note the distance between red longer vertical line in the boxed area is very wide:

Second example of picture of this long R5x w/ GPU heatsink I am looking for and P/N FRU does not matter.

The one is not what I want and is true for all types of other heatsinks by distance between longer red vertical lines is very narrow. No, I do not want that one at all.

Here's the photo for clarification:

These heatsinks has no gap in the area I marked out and this is mistaken as long but this is for northbridge stuff and does not have GPU design. There is short heatsink based on this design as well.

PS: I have the parts ready to assemble a frankie but I'm short one R5x long heatsink or a dead R5x with long heatsink as explained.

YOU want to teach ME about T43/R52 differences?
Well, you got it wrong!
The height of the long and the short R52 fan-grills is identical.
The Intel fan-grill has one fin less than an ATI fan-grill (on the mic/headphone side)

Regardless, I just opened my R52 Frankie with T43 mobo and instead of a T43 fan, I found a nice long R52 fan in there (26R9076/26R9118).
Finding how rare these are, this just upped the selling price of that machine!

Hi RealBlackStuff, I edited again to clarify why I do not need another working complete R52.

I'm referring to distance between red longer vertical lines on the heatsinks to tell apart long and short R5x heatsinks for other owners to identify easier without having to take apart the computer for a look.

Well, I hate to say this, but your gibberish makes absolutely no sense!
And those pictures show no difference either, other than some thin foam rubber strip only LOOKING differently glued on.
Are you using Google to translate the text you want to post here, from a foreign language into English?

I have 1 T43 long heatsink idk if it works in R52 but with one drop act: it produces noise when spinning down sometimes. I bought 2 because I thought I need to replace my two T43s but it turned out that only one of them needed to be replaced.

FYI: T4x series heatsinks are copper & aluminum fin hybrid and designed for thinner chassis. R5x series uses all copper heatsinks and taller height hence the best cooling that my reason to choose over T4x series notebooks.
