Windows 7: HP dv7-1444us laptop fan noise

HP dv7-1444us laptop fan noise

I just began to hear a fan noise about 3 days ago on my Hewlett Packard dv7-1444us laptop. I am pretty sure it is the fan as I know how the fan sounds and it is not sounding like it used too (instead of the hard drive). It's making a constant whining noise now most of the time. Once an awhile it takes a little while to start making the whining noise. I downloaded the HW Monitor program and it has these stats:

Value Min Max

Compal 30FC TZ01 58C (134F) 56C (132F) 63C (145F)
(not sure what Compal means)

AMD Turion X2 RM-75 Core #0 58C (136F) 58C (136F) 70C (157F)
Core #1 58C (136F) 58C (136F) 70C (157F)

WDC WD3200BEVT-60ZCT1

Assembly 35C (95F) 31C (95F) 36C (96F)
Air Flow 35C (95F) 31C (95F) 36C (96F)


Tried turning off the fan in the BIOS but no luck as it still kicks in. Was trying to turn it off to make sure it was the fan by the noise going away.

Downloaded Speed fan and don't see any fan readings at all or I don't know how to use the program

Downloaded the Service Manual from HP, and of course the fan is the very last thing to get too after taking the entire laptop apart! Also found a video on Youtube of a different model but almost exactly like mine being taking apart! Looks scary and exciting at the same time. Why did they put the fan in such a hard to get to place? Hard drive is right there after taking out about 6 screws as I did just to take a look!

Any diagnostics program I can run to make sure it is the fan?

Thanks for your help! Any suggestions from this great community is appreciated!

Can I continue to use the machine. The noise is driving me bonkers, wish I could turn it off and maybe get one of those laptop portable fan things.

Can access all programs etc... as normal, but can't use processor intensive games etc.....because I am scared it will over heat and die! Which it might do anyway. Hope not!

It sounds like the fan is constantly spinning at a higher RPM than you are used to or that there is something caught in the fan. You might want to get a bottle of the computer cleaner and blast it into the fan to clean it up

Do you mean the can of air as I have tried that and no luck. Is there a different type of cleaner you are talking about? Running the Hard Drive test in the BIOS right now just to narrow it down to the fan and possibly make sure it is the fan going out. Have my big home pedestal fan blowing on it as it is going to take a little over an hour to run the HD test, to hopefully keep it cool. And than I guess the memory test just for good measures Has anyone replaced a fan in one of these laptops?

The whining noise is awful

Thanks once again for your help!

Yes i was talking about the can of air and i have replaced laptop fans before but not that one but their all about the same

heres a link to a video you may find helpful. it tells you how to take the computer apart. then you would disconnect the fan from the motherboard, unscrew it and insert a new one.

I also forgot the Power for the processor in the list above!

Powers
Processor - Value 4.80W Min-4.80W Max-31.50W

the Value changes sometimes between 4.80W,11.50W.31.50 but mainly stays on 4.80W

which is weird because when I run the HWMonitor program on my brother in laws dual core AMD the Value and Max are usually about the same wattage. Is this a concern or something wrong here.

This is the video along with the one you posted! Would most here try this?

Although a different model exactly like mine almost.

Can I use the machine with my big pedestal fan helping cool it down. I am using it right now to post this message!

Thanks! Once again the fan is the last thing to get too, inside this model

I guess the fan will eventually stop working. Which is not good either!

Ran the hard drive test and all passed!

Depending on what your doing ie. playing games, surfing the web, or watching movies. these will all require different amounts of power to this is fine
