Thinkpads Forum

I'm building a frankenpad with a T61 4:3 integrated-graphics board into a T60 15". I'm trying to keep costdown on this one, but am thinking about improving the cooling - or more specifically, making it as silent as possible during light use (mostly browsing). I’ll be using the middleton BIOS and a T9300 CPU though. Couldn’t resist

I have the T61 integrated HSF that came with my donor machine. I've seen two tweaks suggested:

1) Use a T61p (or other T61 discrete?) HSF instead of the integrated-graphics T61 HSF. Supposedly this one is beefier or has an extra heatpipe(?)
2) Use a T500/W500 fan in the T61/T61p HSF. I see the 500 series fan has more blades and have seen comments about it being quieter.

My questions are,

A) Will any of these mods result in a more silent machine with light use (word processing, photoshop, browsing with way too many open tabs), when using TPfancontrol?
B) Which of these mods will give the greatest improvement in noise level?
C) Can anyone confirm the T61p / discrete HSF fits well onto a T61 integrated 4:3 board in a T60 frankie?
D) Has anyone had success purchasing a lose high-blade-count 500 series fan on ebay?

In relation to purchasing a loose fan I noticed a number of sellers are advertising 500 series fans that have the same blade count as the T6x fans, but there are a couple of fans that look about right like this one http://www.ebay.com/itm/New-IBM-ThinkPa ... 4ac69b23e6 Downside is it comes with no labels and I’m wondering if it’s some kind of low-quality knockoff. Maybe it’d be better to purchase a used 500 series HSF and gutting the fan?

I've found the T61p fan works very well. You'll need to make a small modification to your retainer so it will clear the larger heatsink and remove the silicone pad that cools the discrete boards chipset and replace it with some good thermal paste so it efficiently cools the integrated chipset/gpu on your intel board.

I've found when properly fitted the fan will only run under heavy use on a unit with the same configuration.

Thanks Tuus.

I went googling on my own as well and saw the German Thinkpad Forum's wiki talks about using a slightly modified T500 HSF (not just the fan unit, the whole thing). http://translate.google.com/translate?s ... ad&act=url
At the bottom of page 4 is a post detailing the fins that need to be removed (go to the non-translated url to be able to see the full-size images). Looks like a no-brainer.

They specifically talk about an intel-GPU board like I have with the T500 discrete HSF 45N5492. The same is covered by "iwishiwasinwhistler" in this thread: http://forum.thinkpads.com/viewtopic.php?f=29&t=101788

The 45N5492 HSF are available en masse on ebay at low prices (from $15 or so). By going this route, one gets the new fan blade design and a 3-heatpipe HSF with same (or better) performance than the T61p HSF, all at a very reasonable price, at least that's the plan

dont forget to undervolt you CPU

It Will reduce temps by quite a bit!

About that... how to do undervolting with w7 x64 ?

Questions:
- Will that special (hacked?) signed 64-bit vista driver work in w7?
- What exactly is involved with using half multipliers in RMclock, seeing as I have a T9300 CPU ?
- Has anyone tried using Throttlestop instead of RMClock? With W7-64?

Also, bonus question - I had RMClock running on one of my W7-x86 systems, and on every reboot, it would ask me for some kind of administrative authorizarion to run RMClock - is there a way to get rid of that prompt?

I use it with Win 8 x64, so i think it will work

I think it will only clock Down 100 MHz, nothing else..

Not me

Should be possible in the Computer Adminstration under control panel.
