Trying to find a good CPU fan + heatsink replacement - and the best way to set it up

I am completely new to PC building, and have received an old Advent QC7003 which needs a lot of work, but is better than my laptop so I feel it's worth it.

I have cleaned out the PC using a can of compressed air, and when I ran some tests it would run at around 90 degrees Celsius, and has had a history of random freezes.

I am thinking that a new CPU fan will fix the problem. The current setup with the case it came in has an Intel Core 2 Quad Q8200 with an LGA775 socket, and a DG45ID motherboard. It originally came with a small, top-down Cooler Master CPU fan which is surrounded by a plastic tube that leads to a vent on the side.

There is a fan in the PSU which is situated at the top at the back of the case, and below that is a case fan with vents at the rear also.

The current CPU fan, which I am planning to replace, is a top-down one. I want to use the Cooler Master Hyper 212 Evo, but since it is a tower-like model I am unsure of how to place it in my case. If you have any ideas on how I should place it, or any recommendations for excellent top-down CPU fans, please let me know.

I have been doing a bit of research into replacing CPU fans, but any advice would be appreciated.

Thanks.

EDIT: This PC is old, from the Windows Vista era. We have upgraded to a new computer, and I thought I'd try and fix up the old one as a project. It's been having problems for quite a while.

Somewhere on the fan housing there will be one or more arrows printed. One arrow will indicate the direction of airflow, the other, optional arrow) may indicate the fan rotation. Even if they are not present, a simple test by feeling with your hand will indicate which direction the fan is moving air. You ca simply flip the fan front-to-back to reverse direction of airflow.

The way I got started with building PCs was way back on an 850 MHz - yea, that long ago. AMD machine. THe case was too hot and I used a drill and a Dremel tool to make holes in the front panel of the standard vendor's case to add a fan and improve airflow.

From there the bug bit and I never looked back. :)
Place the cooler master fan so it blows air through the heatsink towards the case fan at the rear. You may also want to consider how cool air is supposed to enter the case. In the usual custom case design, cool air enters either from the front or the bottom.

However, from your post, it sounds like there's more than just ventilation issues here. Those temps are quite bad.

So you're saying I should set the fan to take in air in front of the heatsink so it will blow air through the heatsink out towards the vents at the back? Also, how do I change the whether the fan takes in air or blows it out?

If it's more than just ventilation problems, then what should I do?

Should I upload some photos of the PC?

By the way, my case is not custom, it's stock. I could try and move it to a new case but I'm just a beginner so it would be quite a task.

So, since you said my temps look especially bad, what do you think the problem is and how can I solve it?
