T60 41V9932 redesign fan?(pics)

[ronan_zj]

hmm, maybe some ppl have posted this question which i am not sure.
I just google the part number for my T60 Fan(for X1400), and I get two different types of T60 Fan. Does anyone know if this is a new design?
here are the links to the pics:

http://www.trialsangel.com/lenovofan/fan2.jpg

fan1 pic is an old desin, and Fan2 looks a new design to me coz the two heat pipes cover two vents.

maybe Fan1 is for X1300 card and fan 2 is for X1400 card? if so, why they use same part number.

I am using the fan2 for my T60 now and I feel this one is quieter than my first fan which I am not sure if it is fan1.

[propellen]

yes, I've got x1400 and my fan looks like the one in pic2.

[gunston]

does FAN2 has a better cooling effect other than noise?

I must be blind, because I can't spot any difference. (???)

Seems like two internal revisions of the same part. I seriously doubt that there are any noticeable thermal differences.

If you look closely, the two heat pipes curve differently around the bottom of the fan, closer to the fan opening, maybe to better transfer heat to the fan cover.

That's also what I believe. My T60p have the fan1. A longer heatpipe for the CPU is useless because it runs much cooler then the GPU.

All T60(p) with dedicated graphic use the same fan assembly (same FRU).

Actually there was never a re-design of fan for T60/p as the topic of this thread suggests. Only a slight modification was made in late 2006 for Widescreen models which due to this and being spacious runs cooler than their counterparts.

The fan is redesigned just recently for *61 models.

I may order a new HSF for my T60 because I just upgraded the CPU fro Core Duo to Core 2 Duo, and the old HSF wasn't able to keep the CPU running cool. Is there anyway I can tell if the retailer is selling fan1 or fan2 before I place my order?
A google search returns two FRU number: 41V9932-02 and 41V9932-06. Anyone know which one is fan2

Maximum TDP for Core 2 Duo is 34 watts and 31 watts for Core Duo. So, except if you install the most powerfull Core 2 Duo, your fan assembly can handle the new CPU. This can be a mounting issue. Check if it's correctly screwed and also if thermal grease is still there.

Anyone knows if a T43p TDP fan is different than a T42p fan ?

That's what I though at the beginning. I tried re-mount a few times, and I used AS5. Don't know why load temperature of the CPU is 40C hotter than idle temp(50-55C idle / 95C load with two super-pi or multi-threaded applications).
It seems my HSF (looks the same as fan1) is cooling the GPU well (GPU idle @70C, and 85C load ), the difference is that the CPU's heat pipe only covers one vent while the one on GPU covers both.

Try reinstalling the chip. I've noticed that with these types of sockets you need to put a bit of pressure on the CPU to make sure it doesn't move or back out when you engage the socket.

According to what I read, the *new* fan assembly with a longer heatpipe seems to used form T60 update to Core 2 Duo. This is (I suppose) to handle the extra 3 watts. It's about 10% more so it's albeit significant.
Do you check the fan rpm with TPfancontrol ? Perhaps your fan did not run fast enough...
Do you have the last BIOS update ?

The BIOS version is the 2.16. Both TPfancontrol in Windows and ibm_acpi in Linux show that my fan is running at 2900, 3400 and 3800-3900rpm depends on the temperature. I can try to push the fan speed up to somewhere around 4200-4400rpm if I manually set the fan state into "disengaged" in Linux, but it doesn't make a lot of difference and the rpm is not very stable.

I'll try that.

According to Hardware Maintanence Manual heatsinks for Core2Duo laptops have different FRU, 41W6407. I've found a picture of one on eBay: http://www.ljplus.ru/img4/s/i/silencers ... atsink.jpg
