R50P GPU Cooling
R50P GPU Cooling
I think I looked through every R50P fan and/or cooling thread in the forum but I didn't find this information. My R50P (new to me) is currently running Linux. If I run a 3D application (like glxgears for example) the GPU temp approaches 95*C or higher. I looked up the cooling fan for the R5X Thinkpads, and it is part # 13N5182. It is a short fan (different from T4X fans as far as I can tell) and there is no direct GPU cooling. That is the only fan listed for the R5X series. It's amazing to me that IBM passively cools the GPU (FireGL T2 128MB - Rad 9600) in the R50P, but offers a long fan to cool the same GPU in the T4X/P series. Am I missing something? Is there a 'long fan' for the R50/p? If there isn't one available, that tells me that this machine was never designed for 3D apps.

How do you measure the GPU temperature? I have the R50p for a very short time, but I've played 3D games for some time already and I don't see a problem, I've been trying to measure the GPU temperature with atitool and NHC, but I can't get it work, I actually don't want to use the tpfancontrol, I don't like messing with my BIOS , but I'll try it if it's the only way, If I can get the temperature monitor wokring, I'll check out the temperatures on mine. (Just for info - the NHC is reporting the HDD temperature about 38-40 and CPU temperature under 40 when iddle and about 71 when at full load - during 3D gaming for instance)

You don't have to mess with the fans when you use tpfancontrol, you can just look at the temps.
There is an R50 fan that has direct GPU cooling:

It appears to be a new thing, most of the machines appear to have come with a separate passive heatsink.

In the R50p's that I have looked at they all have direct GPU cooling. In a similar configuration to the T4x long fan the R50p long fan directly cools the GPU. Maybe your long fan has been replaced with a short fan.

That long fan in the link seems to be made to cool the northbridge. Maybe for models with integrated graphics.
The HMM for the R50 also doesn't mention more than one fan(the short one) but differentiates between a simple clip and and heatsink for the different graphic chips.
I have read at least one thread here where other people complain about the insufficiant cooling of the R50p and even claim that it broke because of overheating.

I just tried some extensive 3D gameplay on my R50p, as it's from ajkula66, I'm certain that in this one wasn't the fan replaced with any unapropriate and according to the tpfancontrol, the GPU temperature during gameplay was 96*C, so it appears to be normal for a stock R50p. As I read some opinions now, the 96 degrees is not as critical for a GPU as it is for a CPU, of course, lower would be better, but now it seems to me that the R50p was designed for these GPU temperatures....

I have the longfan from a t43p and the mainboard from a t43p in an R50 case an it works better (runs cooler) than in a T case.
I wasn't at all taken by the standard cooling solution and to be honset it sucks. I tested both.
It will block the firewireport though, which the r50p doesn't have anyway.
You have to replace the rubber on top of the fan which supports the keyboard as the case of the R is thicker.

OK let me chime in here real quick...
I've been asked many a times what I think of GPU cooling in these machines, especially under Linux, and I shrugged my shoulders every single time. Now I understand what people were talking about...but the fact of the matter is, I don't play games and never have...
All but one R50p ThinkPads that I've sold on this forum have come from the exact same source, and have behaved similarly in most respects, including the heat issues, that I've detected none whatsoever in my "normal" use. I have noticed, though, that they get hotter under Linux than under XP with no gaming involved.
Given that the mobos are interchangeable between T42p and R50p, I see no reason why one wouldn't be able to replace the fan with the long one, even if it takes some finagling.
Just my $0.02

So, I'm I getting it right?: I plan to upgrade my R50p to dothan in the future when I'll have some spare money, when I'll be doing this, can I just buy a T40p, T41p or T42p long fan and fit it in the R50p? And should I avoid intensive 3D usage till that time to keep my r50p safe?

No, I think the R50/P fan is different than a T4X/P long fan. I think you want the part number mentioned in this thread instead. Anyone disagree? I'd like to be proven wrong for financial reasons .kajencik wrote:So, I'm I getting it right?: I plan to upgrade my R50p to dothan in the future when I'll have some spare money, when I'll be doing this, can I just buy a T40p, T41p or T42p long fan and fit it in the R50p?

hmm, so I found this one: here
That seems to be the correct one, and even the price would not kill me, I'll go for it if it helps to lower the GPU temperature, can someone confirm that this is the right one I need?

Thank you for your effort Let us now how it went.aaa wrote:Well I have a T4x short fan in there right now (I don't have any firewire to block), and I'm going to try out the T4x long fan eventually..
Also, it seems like the T4x fan might be difficult to put in without removing the entire palmrest.

DarkMark and aaa, I did a little poking around and here's what I found. When you say that the long fan cools the northbridge (not the GPU) on the R50 series, I think you may be right. If you study a picture of an R50 motherboard (Pic 2 linked below) and look at the placement of the northbridge vs. the GPU, you'll see that the GPU is off center and the Northbridge lines up to where the long fans extended heatsink would go. It's a straight shot back. Even the pad on the extended heatsink is tiny, as in the size of the Northbridge (Pic 1 linked below). Look at these 2 pics and see if you don't agree.
Pic 1 - R50 Long Fan
Pic 2 - R50 Motherboard
Note - for a reference point on the motherboard in Pic 2, the round cutout is where the fan goes.
Looks to me like the GPU (labeled ATI) is to the right of the Northbridge. If anything, it looks like a T42P long fan (Pic 3 linked below) lines up better with the R50's GPU because the extended GPU heatsink is offset. Not knowing the dimensions and screw hole placement, etc. it's anyones guess if it fits ...
Pic 3 - T42P long fan
kajencik, at least you can now see that they are completely different fans. Someone would have to actually try putting a T42/P long fan in an R50/P to see if it's a fit. The downside is that even if it does fit, what now cools the Northbridge? If you take that cooling off of the Northbridge, it may make the machines stability worse. It's definitely there for a reason. Kind of a catch 22 eh?

I personally think it the t42/3 longfan would fit in an r50p.
I already tried it the other way round,w ith an r 50/p fan on a t43p systemboard. Also the screw holes all line up. I even think they used the same pcb layout, because the t43p mainboard has the firewire solderpads where the connector would be on a R50 and we all know the t4x series never had firewire.
I also don't think it will do much harm not to have the northbridge cooled, since I think it only needs to be cooled when the graphics solution is integrated into it.

As I have read several posts here, I think that the R50p and T42p mainboards are , if not excatly the same, at least very very similar, so IMHO the only one question is, if the T42p long fan will fit and hold in the R50p case and screw holes...

The fan with northbridge cooling would not fit in the R50p, as there is a plastic bridge going across the northbridge.DarkMark wrote:I also don't think it will do much harm not to have the northbridge cooled, since I think it only needs to be cooled when the graphics solution is integrated into it.

I was able to fit a t43p fan in an r50 case with no problems.
In any case it is thinner than the original one so you need a thicker rubber between the fan and the keyboard.

That original rubber should be thermally conductive. If you use something else, you may lose the keyboard cooling surfaces.DarkMark wrote:...

So we almost have it Anyone knows with what should be the rubber replaced? Would it be enough to use the new one on the fan along with the original one? Or it's a separated part?

I've done some more research now, I'm almost convinced to buy the T4x long fan and give it a shot, the last problem I see is something like the termal rubber as mentioned above, as I'll need more of it for the Tx fan to fit, anyone has an idea where to get it, or at least how it's actually called? I've done some ebay and google researches and it seems that I just don't know the right term for this...
