running it with the battery removed to see of the fan slows down or stops. Sometimes an old battery keeps demanding current from the charging circuit and causes extra heat. If this solves the problem, you'll have to buy a new battery or always run on AC w/o battery.
Also ask uni techs to check if fan bearings are worn. If so your only recourse is to replace the HSF unit.
I've been using my IBM Thinkpad T61 for almost more than 2 years now. I received it from my university. It's been doing great for me, both for my educational needs and some multimedia needs.
Recently for the last few months, it's been making this weird noise near the fan. I thought it must be from the fan as it gets clogged by dust over time. So, I sprayed Falcon Dust-Off on it, both on the keyboard, mouse pad, on the sides where I believe the fan is located. Then, in the past few weeks, the noise level has increased even more. It occurs mostly when I keep my laptop running for maybe half an hour or more. It goes for some time and then no sound for some time and then over again.
I took it to my university's IT dept to get it checked. They also found dust inside. So, they opened the hardware inside and sprayed Falcon Dust-Off. Now, this week again, the noise is occurring to the laptop. A friend of mine told me to get a laptop cooling pad so that my laptop's noise is reduced if the fan is cooled properly because on the left side I feel heat coming out.
I'm thinking about buying a Logitech or Antec cooling pad that's in sale in Staples during this Back to School sale season. But I am worried that would it stop the noise and reduce the heating or no effect at all like the previous methods tried out before. Nevertheless, is a laptop cooling pad worth to buy for such problem?
I'm not that of a techie guy, so not much experience with computers really. If anyone can help me with the problem, I'll really appreciate it.
PS - I mostly do typing, instant messaging during school season. Other times I use it to download and watch movies or listen to music online. I thought this information might help the experts to figure out my problem.
