Thinkpad T530 - Fan Comes On As Soon AS Compter Turns On

#1 Post by NothingNew1 » Sun Sep 08, 2019 9:30 pm

Hello,
Picked up a T530 from ebay and the fan turns on seconds after the computer boots. What could be causing that ? Is it a easy fix ? Someone suggested cleaning and putting new thermal paste on the CPU. Has anyone else had this issue ? The computer itself is in great condition and so far running great except for this issue.
Any help or advise would be greatly appreciated.
Thanks !!

Nearly every Thinkpad fan comes on for a few seconds when it boots.
If it stays on, it's running too hot.
The first thing to do when you get such an oldie, is to clean fan and CPU and put fresh thermal paste on.

Recommend installing a temp monitoring software. For Windows HWMonitor is a good comprehensive one. TPFanControl also reports CPU temp on the T530.

Idling should be around or under 50C. 70C to 80C is hot but normal under sustained load.

Always wise to repaste a laptop that you buy used. Some tend to have the original paste that was never replaced, or have its heatsink dusted. It's bad when it's solidified and becomes a chore to scrape off! Unless you get a plastic spudger used to remove car decals, it could make that job easier.

When you repaste, give the heatsink fins a good airdusting too. I use Arctic MX-2 for my units and give them an airdusting when I acquire a "new" laptop.

It's also noted that those with dedicated graphics chips, such as my 8470P or my old MSI GT640, also emit heat and has only one fan to manage both GPU and CPU so they'd also be noisier as a result.

I reapplied the paste, let it sit for a bit, but the fan is still running all the time. The average temp is : 45-47 degrees C. It never reachs "high" or "critical". Those are the read using Linux
$ sensors.
The insides of this unit, actually looked brand new, it was spotless. Any other advisce on what else it could be ? Also, if it decides to up and die on my any other suggests of Thinkpads in the $100-125 range ? I'm new to Thinkpads, but will say I'm happy with the T400 and really love the T530 except for this issue. I'm very tempted to buy another one and make this one a pet project to try and fix to proper working use. Oh, any reccomendations on good ebay sellers ?

Maybe the heatsink does not sit properly and flush on the CPU?

45-47C are normal idle temps. The question is - should the fan be running constantly at those temps or not?

Right now my X220 has CPU @54C and fan is running @3600RPM. It's rather quiet, though.

Does the fan respond to manual controls as described here:
http://www.thinkwiki.org/wiki/How_to_control_fan_speed

I also second the suggestion to try TPFanControl (booting into Windows).

Perhaps it's normal to have the fan run, but something might be wrong with the fan which makes it loud.

Silly question, but the GPU isn't overheating right? Even with my i7-3720qm 45W beast the fan shuts off when the temps is at around 45 and only turns on when the temps are over 50

My T420 likes to run its fan at 3200 RPM (equivalent to Manual 2) even with the CPU at 43C near-idle. It's the stock 4 pin Toshiba fan from the monopipe heatsink.

IIRC the dual heatpipe heatsink with its 3 pin Panasonic fan is quieter, when it's working correctly.
