M24 Long fan vs M10 Long fan - Difference?

Message

I just recently upgraded my T41 w/ SXGA with a t42p motherboard w/ 128mb Fire GL video and I used an M10 Long fan with the setup.

I am going to be doing the same upgrade with another T41 w/ SXGA and I just wanted to know if there was any difference with the M24 Long fan that comes with the T43 compared to the original M10 Long fan that came with the T42P? Are they identical?

The part you need is FRU #41W5204. (This is a substitute for 13R2657, which is no longer available).

The difference from the other "long" fans is that the above part has the largest "footprint" on the graphics chip.

Strongly recommend wiping off the IBM heat compound for the CPU and using Arctic Silver 5. Apply evenly but sparingly to both surfaces (CPU and heat sink).

On the graphics part of the heat sink, there is a pink plastic sheet. REMOVE THE PINK SHEET. The dark brown heat compound will melt and bond onto the graphics chip.

You should consider removing 1/2 inch square from its center and using Arctic Silver there as well. Leaving an 1/8-inch perimeter of the original material will insure "bonding".

Good luck.

Where can I find this fan? Will the T43 fan not work? I'm just trying to find one on ebay.

The T43 fan is not identical; I don't know if it's close enough not to matter.
If you wish, send me a PM (Private Message) with your address and I'll send you a new 41W5204.

Hey EOMtp...it looks like the t43 fan is the same fan but it has a bigger cooling channel that goes to the video side.

Another question: You mentioned to "remove the Pink Film"...why is IBM leaving these pink films on at the factory and installing them with it on. I do believe seeing a heatsink installation guide and on that it says "remove" the pink film. Is that thin film some kind of thermal pad? If I remove that film and let the compound melt onto my chip....will it be hard to remove next time?

I know that IBM places a thermal pad on the GPU portion to the long heat sink. I suspect the reason is that removal of the heatsink from the GPU in the future is easier that way.

I have always opted for the best heat conductivity. That requires the least material between the the heat source and the heat sink.

Removing the heatsink is not difficult even if it was mounted without the thermal pad. The compound is not like epoxy, i.e, one can remove it if/when needed.

So is the part # above for the m24 or m10 fan? Also, would this fit a t41? and if killer doesnt want it, ill take it

FRU #41W5204 is for the M10 and it will fit a T41.

Tony (tnynyn): Check your PM (Private Message).

thanks for the info. btw, didnt get any pms from u yet. could you please resend. thanks again.

Tony, You did not receive my PM because -- for some reason -- I can send PMs but not to you. Send me one and I'll reply ... let's see if that works. If you wish, include an e-mail address and I'll contact you there.

Hi, i recently had my mobo replaced from the warranty work they did... I have a t41. They put in a T41p motherboard in by mistake. So does that mean i will have gpu heat issues????

cause im pretty sure i have the heatsink and fan that orginally came with my laptop... though im not very sure, pictures would be nice to use to compare... but i can't find any. Not sure how to monitor my temperture, though i dont really use my t41 for gpu extensive things. Although id like to keep it up to spec.

thanks.

The difference between the "long" fan and the "short" fan is an extension of the heatsink/fan assembly to the GPU. The short fan covers the CPU only, and is rectangular in shape. The long ones have another small rectangle at the lower right-hand corner, located roughly under the 3 trackpoint buttons below the spacebar.

Anyone try the M24 long on a T41p?

EOMtp · #15 Post by **EOMtp** » Wed Aug 09, 2006 1:14 pm

Perfect fit.

Any way to find that online? Am I correct in saying that the T43p has a beefier heatsink?

EOMtp · #17 Post by **EOMtp** » Wed Aug 09, 2006 2:31 pm

The differences between the M24 fan and the M10 fan are insignificant. The M24 heat sink has a marginally smaller GPU pad with a marginally wider heat "pipe" leading from it; the CPU section is identical. 1mm in either direction cannot make much difference to the heat sink's performance. The fans are identical.

Thanks. In that case there really is no point. Saves me a couple of bucks

Any reference to know which heatsink is the better for my T42p who is suffering from freezing problems when gaming??

What's the point in having the small heatsink if it don't cover the gpu?? Surely, the GPU will overheat ?

No need for double posting.

The heatsink that comes with your T42p would be the best one to have. The freezing problem might be due to a lot of heat being put out by your cpu during gaming.

Sorry for the double post.

My machine is under warranty, and next Monday I will send the laptop to have the fan replaced by the long fan:

(look at the right bottom, there's the heatsink for the GPU, guess mine right now is the short fan.

Also, there could be no good interfase between the GPU and the heatsink that's why there's too much overheating.

Will post again when this is fixed **hopefully**
