Laptop Cooling and cleaning

Posting this just in case anyone else is having the same issues.

I have a HP Pavillion ZV5000 series, and it was running extremly hot. I have a laser thermometer and the temp coming from the fans was 114F. While not insane it, was really hot, and roasting my you know.... The fans seem to be on all the time and even people at work were commenting on how loud it is.

Last night I decided to take the bottom off and take a look. Firstly it was nice that the bottom is split into sections so you can remove just the section over the fans. It looked a little dusty but not too bad. Well I vacumned out the fan compartments... I pulled out hunks of dust the size of a cat! Hmmm..... I might actually be missing a pet!! Anyway.... after vacumning out both fan compartments temps are MUCH lower. 75.5 F as opposed to 114F.
 
If I'm not mistaken, the zv5000 series is P4 based. Of course it is going to run hot.

In fact, 114F (~46C) isn't very hot for a P4 notebook; but then again you're not measuring CPU temp. DL a prog called Mobile Meter and use that to check CPU temp. Anything around 60C is fine for that P4 IMO; those bastards run hot!
 
That whole series runs hot. I had a ZE4210 celly that roasted as well. Fans was always on and loud as hell. Good thing I picked up a Dell Inspiron 1100 on the cheap so I can go through that heawave all over again. The HP nc6220 that I use for work is great, the fan is almost never on... unless I'm doing something taxing on the CPU.
 
You are correct, it actually is a P4 3Ghz Northwood with HT. Because it doesn't have speed step it never slows down.

Thanks for pointing out Mobile Meter, it is nice to be able to monitor the temp of the CPU properly. It's running around 52-56C.
 
I use my laptop in a hellish factory environment (Hot, humid and dusty), and even my fans accumulated a lot of dusty.

I have to clean the fan and the place where the air hits the air fins every 2-3 months or so. Dust balls form if I dont, and increase the temperature and fan frequency.

Good thing that in my laptop, the fan can be taken out by removing 2 screws from the bottom, so its easy to clean.
