Hi guys,

I'm going to be using this case to put all the components from my current PC in since my current case isn't big enough to hold the new graphics card I'm ordering:


Now, the case says it includes a rear fan and has slots for a 120mm front fan, two 120mm side fans and two 140mm top fans. Am I correct in assuming that putting a fan in every opening will give me the best cooling possible?

I have the following fans in my cart along with the case:

Three of these for the front and side: http://www.newegg.com/Product/Product.aspx?Item=N82E16835200049

Two of these for the top: http://www.newegg.com/Product/Product.aspx?Item=N82E16835233036

In case it matters as far as how many fans I can use here are my motherboard and PSU:

Motherboard: http://h10025.www1.hp.com/ewfrf/wc/document?docname=c02980014&lc=en&cc=us&dlc=en

PSU: http://www.thermaltakeusa.com/Product.aspx?C=1247&ID=1898#Tab0

Now, two questions.

1. Are those decent fans?
2. How does the "flow" work? Is the front fan intake and the side and top fans exhaust? Or are the front and side fans intake and only the top fans exhaust? Along that same line, if a fan is supposed to be for intake, how do I make sure I install it in the proper way, and vice versa for an exhaust fan?

Thanks in advice for any help.

Hi, Ask yourself this question. How many fans did HP put in my old case and it was fine with them.

Normal I would expect from HP would be Power supply fan, CPU fan, and maybe a case fan exhausting out the back.

Why do you feel the need for so many fans?

Any Video card you buy should be exhausting the air out the back of the case.

Also make sure any fans you buy are very quiet and can hook up to the power supply. The Stock HP motherboard will never handle that many fans.
Good Luck

I would get the case and go from there, sometimes especially with hotter running video cards or cramped cases, you need a lot of fans, but often you dont. In some cases, having to many fans can actually work against you. I have a lot of fans in my system-but Im running both a crossfire setup and a RAID array, and the added cooling is a necessity. other then the stock specs in your link, have you added anything such as video cards? that setup should be fine with maybe 2 fans, one intake and one exhaust, especially 120mm fans, if you have a aftermarket card what is it and I might be able to tell you what Id use with your system and your case.

Ideally, you want air moving from the front/bottom (if you have a bottom vent) of your case up through your case, and exhausting out the back/top of the case for best cooling, if you can accomplish proper airflow with 2 or 3 fans to keep everything cool enough, then that would be best-otherwise your systems going to sound like a jet airplane taking off (trust me, mine does, I just use mine for gaming primarily and with the sound turned up I cant hear it)

I'm going to be installing a Radeon HD 6870 video card. I actually switched my order to a Rosewill challenger case which comes with a front, top, and rear fan pre-installed. Problem solved. :)
