Replacing a fan in compaq presario

[Margo1]

Hello!

I am attempting to change a 80mm fan in my Compaq computer. The fan I want to change is, I believe, called the CPU fan. It has a lever next to it and 4 screws holding it down.

My question is this: Do I have to move the lever on the side of the fan in order to pull the fan up and proceed to remove the screws or do I just remove the 4 screws?  Also, how do I remove the screws considering the awkward position they are in?

(I've been working on trying to remove the screws; however, it is difficult to maneuver the screwdriver into the top of the screws to remove them. This is because part of the fan case is above the screws making it necessary to place the screwdriver sideways in order to remove the screws.)

Thank you for your response.

Welcome to HP Forums, this is a great place to get support, find answers and tips,
Thank you for posting your query, I'll be more than glad to help you out 🙂

As I understand the CPU fan is being replaced and you want the Do's and Don'ts about the same,

I will be able to provide limited support as HP doesn't recommend replacing the fan on your own as it may impact damage upon other parts,

Nevertheless, to answer your question: the lever would remove the CPU, you could do that if you wish to remove the CPU and then the FAN, 

otherwise, you could just remove the FAN by taking off the screws rather than pulling the lever,

Hello and thank you for your response. I am reading the link to the article but I still have some questions.

The reason why I am asking about removing the fan, which upon further research I think is on top of a heat sink, is because I've already replaced the 90mm case fan and the power supply unit (which has a fan inside of it), thinking that they were the cause of the fan noise I began hearing some time ago. When I contacted the seller of the power supply unit that I recently installed, he told me that the noise could be coming from the fan on the CPU.

If I just change the fan, do you think the fan noise will stop or must I also replace the fan with the heatsink? I really don't want to fool around with the processor, and I've already purchased a 80mm by 25 mm fan thinking that I could just replace the last fan in my console that has not yet been replaced. If I have to get into the processor to replace the heatsink, I believe that means I would have to purchase a fan attached to a heatsink, correct?

Also, if I can just replace the fan, how do I maneuver to remove the screws? I do have a Phillips screwdriver, but I still have problems removing the four screws from the fan because of their position.

Thank you for your response.

A smaller diameter phillips head screw drive should be used, straight down into the hole above the screw.

I am going to purchase the screwdriver that you suggested and change the fan only. I will let you know if this works to stop the fan noise on my computer Let's hope:smileyhappy:!
