Replacing the Fan?

[kennyschiff]

My 2 1/2 year-old X61 (7675CTO) has started to make excessive fan noise, in spite of the fact that the fan is not necessarily spinning that fas (3448 RPM). Kind of has a propellorish sound... very winey. The machine is no longer under warranty, and I probably voided that anyway by self replacing the LCD a year ago (I was able to buy a brand new top from someone)... so I've cracked this thing open previously.

Should I just ebay a new fan? is that likely to solve this problem? Would something like this do the trick: http://cgi.ebay.com/Original-New-IBM-Th ... 35a590f0c3

I'm not especially mechanical, but I did replace the screen, so not completely green on this.

I'd go for it ... after looking at the auction thought about buying one myself!

You'll should be OK replacing the fan if you are careful. I took my X60 fan/heatsink off to redo the thermal paste and re-lube the fan. The MOBO has to come out, and while the job looked a little intimidating at the first (never pulled an X60 MOBO before) all went well ... didn't even use the manual.

BTW, do use use a fan control? If not try NHC, works well on the X60 here (even undervolted it).

Good luck

That is the fan only, not the fan/heatsink assembly normally supplied. The only time I replaced just the fan, the unit supplied was poor quality. The whole assembly is 42X3805

@richk: why would I need the heatsink if the fan is making noise?
@sojourner: I've been using the TPFancontrol under Linux

@sojourner, you mention that you undervolted your x60, could you list the voltage/multiplier settings?

I have an x60 with a Core Duo processor and I believe it can't be undervolted. Instead I am forcing it to run only on the 6x multiplier (0.95V) using RMClock.

Hmm, that's interesting. I cannot get TPFancontrol to work with latest releases of Ubuntu. What Linux and ver do you run?

@sojourner: I'm using Ubuntu 9.10. Running tpfand 0.95

I run RMClock in W2k and NHC in XP. Here's the voltage/multiplier settings:

W2K
AC power - performance on demand
FID 6x, VID .95
FID 12x, VID 1.1
auto adjust intermediate is checked
for battery power I only use 6x,.95v
BTW, if you check "run HLT command when idle" you may see better cooling, perhaps better battery life. You may want to play with "Advanced CPU states" too, some people like to check C1E

XP
same volts/multiplier as above
you have to manually set intermediates

Works GREAT!

Ahhh, that might explain it. I got v.82. Where did you get v.95?

Thanks for the info BTW!

The parts come as a "heatsink and fan" - together. The pieces are usually spot-welded, soldered or glued together.
