Background: This is a Dell E1705 (9400). It's 3 or 4 years old now and way out of warranty. Long story short, one of the fans has decided it didn't want to work anymore, or at least work to its full capacity on any regular basis. The left fan (underneath the ESC key) works fine, but it's the fan on the right side giving me trouble.
So to diagnose if the fan is completely dead, I've tried a couple fan monitoring programs - none whatsoever can detect any fan. This includes:
HWMonitor, SpeedFan, hmonitor, I8KFANGUI won't install - driver problem. BIOS (no settings within).
I've tried updating the chipset, nada.
So I can't even tell if the fan just needs some help, or if it's dead, or really what the story is. I'm not even sure how to replace it if that'll fix the problem.
Well, my left fan just kicked in, so I better submit this before the laptop shuts down. I wouldn't be against getting a new one since this one is old, but I'd rather pay $10 for a new fan and replace it if that'll do the trick.
