R500 CPU Upgrade Questions

Quick and easy questions for the experts out there.

Context: I have to replace the fan on my trusty R500. It's ordered. Arctic Silver 5 ordered as well.

The questions:

I have a P8400 CPU. I can get a T9600 on eBay for CAD $18.
  • will my current heatsink/fan handle the upgrade?
  • and is it worth bothering, performance-wise?
I already have an SSD installed, and I've read that the SSD and RAM upgrades make the most difference.

Well, it's not a lot of money to invest IMO, but do bear in mind that a T9600 will run warmer and return less battery life.

Will it be a night-and-day difference in *any* respect? No.

Your ThinkPad, your $$, your call.

Thanks! The money and battery life don't matter, so I think I'll do it.

I have similar machines with P8400 cpus and others with P9600, which is very similar to the T9600. The P9600 gives a nice little boost.

I hate waiting. CPU is here. Paste is here. Fan is not here. :(

On some of my T400's I run coreboot and it doesn't require the fan be installed?!

That must be a very light system. The machine still runs, although the fan kicks in and buzzes occasionally. I guess Debian must not tax the system much either. So it's still usable. I just want to do the upgrade!

So I finally got around to doing this upgrade. The parts came a long time ago, but I got busy with other things, and it seemed like maybe the T9600 upgrade wasn't a good idea for a machine that already ran a little on the hot side.

Well, the T9600 and the new fan are installed, and the machine runs much cooler. Found the culprit: https://flic.kr/p/G6Yqhd

I guess you were right, jaspen-meyer. You don't need a fan. Mine couldn't have been accomplishing anything.

Anyways, right now my cores are running at 36C and 39C, which is at least 15C lower than before.

Edit: I just watched some Youtube, and the cores fluctuated between 40C and 42C. Tasks that used to drive my CPU usage to 50% are now only putting it into the 30-35% range. I'm quite pleased.

Edit 2: Well, I must not have seated the CPU correctly (or I have a different loose or damaged connector somewhere). If set the notebook down (I think bumping it from the bottom is the issue), it freezes. Back into the guts of the thing I go!

Edit 3: Rookie mistake. I thought the CPU lock screw turned 90 degrees, but it turns all the way around to 180 degrees.
