Loud fan/case, wanting better airflow

Here is my front intake fan:

EDIT: THIS cpu heatsink:

I am using this case and its stock (loud) 80mm rear exhaust fan:
http://www.newegg.com/Product/Product.aspx?Item=N82E168...


PROBLEM:
Its all loud and my evga x58 mobo is unable to throttle the front intake fan (not the one on the cpu heatsink). My case says it has a 90mm rear fan...I will measure to confirm.


QUESTIONS:
1. I want better airflow...do I have any options?
2. I want it all quieter...Can anyone make a better 120 and 90mm recommendation?
3. Does it make sense to buy a new case for better airflow...I am trying to keep things super small

I know the case is cheap/junk. I was sticking with it because I want it to be as compact as I can get. The case you recommended looks nice, but is a bit big..

Air flow and quiet go along with larger cases and slower fans. You desire for a small case goes against both of those criteria.

The Illusion is just 2" bigger in height and depth and 1"in width whereas the HAF is bigger by 6", 4" and 3" . The Antec 300 Illusion is a quiet case, and my only beef about it is still no front USB 3 port It's also only $49

As for fan swaps, the Illusions are just fine..... read about alternatives for your case here:

I think the case you have is fine. It has a 120 on the front, and a 90 on the back, which is sufficient if you aren't doing any overclocking.

Since the MB won't control the fans, you may want to just use a fan controller.

Or you could change the front 120 to this fan, as it comes with a controller. I have 3 of them, and they work great. At low speed it is not loud.

Change the rear fan to this.

The pic on newegg shows your case with side vents, but the manufacturer’s website shows it with no side vents. If you case has side vents, you may be able to add an 80/90 mm fan to the side for the cpu.
If you change the fans and get the fan controller, you should have plenty of airflow and low noise.

I actually replaced the top and front panels on my case with thin, pieces of wood. This cuts down on the case height and allows me to still put proper gratings, etc. This also makes my case much shorter (14").

ajt_leo2002:
If those fans are quiet I will give them a shot. The heatsink I have came with a very similar coolermaster fan that also is loud, I will replace it as well.

My case does have a side port for mounting a 90mm fan, but I figured I should remove it and keep my fans to a minimum. I could try to setup my processor heatsink to push air out through it, but it isn't perfectly aligned.

Should I just toss my coolermaster heatsink out and use the stock? Would water cooling be quieter?

The heatsink looks sufficient and the reviews give it very high ratings, so I'd keep it. If the fan is loud, go ahead and replace it. Just be sure to get a fan that is PWM controlled so motherboard can control it properly. Don't flip the fan to have it exhaust the air through the side port. The side port is for bringing cool air in, so if you can add a fan on the side port, that would be ideal. But, if that produces too much noise, skip it, as the air will enter anyway if the port is open.

Oh, I missed the wc question. I have no experience with water cooling, but my quess is no, as you still need fans to cool the radiator, and depending on the set up, those fans could be outside the case.

How are you using the computer? General use, gaming, video related, etc?

this machine is my main machine. I use it for Sc2, ripping/converting movies, general stuff. I do not do any OC'ing, I mainly got the aftermarket CPU heatsink to avoid intel's crappy heatsink mounting system.

I don't know how much good the exhaust fan is doing since the case is so tight. I figure all the air (hot and cool) is just blown around and eventually leaves the case or cools the CPU.

I am an engineer and looking at the typical mobo design, I can't help but wonder what the heck mobo and case designers are thinking when they stick the cpu crammed under the power supply near the top of the case.

Agreed. Case/MB design like that is not ideal. Nor is the small exhaust fan. But, price point dictates design decisions, so some stuff gets the short end.

If the power supply is set up so that the fan exhausts air from the case to outside, then that might be no problem with the case/psu/cpu situation. If it takes in air and exhausts hot air into the case, then that might be a problem, but I doubt that many power supplies are situated like that.

That top exhaust fan, while being small, is still useful. It really just needs to create a draft and pull out enough air for the draft to be beneficial. Bigger would be better, but in this situation, I don't think it would make too much difference to worry about.

I hope all this is helpful for you.
