i have recently noticed sometimes at startup, i get a notice that tells me the comp has cooling fan problems.

 

how do i determine if the fan is going bad or if there are other problems?

 

thanks for any help you can provide.

Hello gregahoffman.

As stated by HP people, this is a known problem >> See this link to HP with the only option being to "blow a can of compresses air" into the end of the computer near the "QWAS" area of the laptop.

NOTE 1 : See that they do not advise you to dismantle the computer unless you are 100% sure that you know what you are doing.

This may dislodge any build up of extra dust Etc. and help to cool or dislodge any build-up when it first starts.

 

Hope this is a good first step.

thats not an option, thefan is stuck on low speed, at boot up, it tries to go full speed, possibly a test for the system, but it can't. it has been very loud and noisy for over a year.

 

i ordered one on the internet and plan on disassembling it and repairing it. i have a HP service manual and also ordered some arctic silver thermal paste.

 

i have installed speedfan, but i cannot force the fan to spin faster.

I do understand ..

 

Please take care when you dismantle the unit, and as you have the HP service manual only do it how they say.

 

I would say "not a test for the system", but more like "stuck in first gear in a car" but it never moves into cruise mode once warmed up. :rolleyes:

It could be simply bearings or bushes in the fan unit are worn out, as most of these units are about 3 to 5 years old (or more), but you do not say.

 

Take care with the wires, as I always tag them when I remove them. Clean any old paste, and only a Very Small dab of new silver paste..

 

Yell back here when you finish as I will keep an eye on the topic.

Good Luck.
