Dual 200mm Case Fan Not Making A Difference?

[-rascal-]

You can't just compare fans by the "feel" of the air going through your hands. That's what you DON'T do.

The Cooler Master JetFlo's are a bit more static pressure oriented and spin at much higher RPM's. The larger 200mm fans rotated at much lower RPM's, but deliver more airflow at lower pressure.

Because of the larger fan blades on the 200mm, you don't need high RPM.

 

Having your front 120mm JetFlo's set up like that does not multiply the air coming in. That's not how it works.

If what you are saying is true, having 40 Corsair SP fans would make this H100i cool the CPU like a Madafooker. Unfortunately, in reality, that is not true.

 

I don't know what CPU and motherboard you are using, but, depending on your ambient (room) temperature -- as it does play a role in your overall system temperatures -- 25*C is considered normal for a motherboard. the SB or NB chipset may be higher (depending if it's overclocked, etc).

 

For my system, with a ambient temperature of 22*C, HWMonitor is showing the following

• 25*C for the Mainboard
• 33*C for the SB chipset
• 45*C for the NB chipset (I do have it overclocked and overvolted)

No the thing is I purchased a $150 case to receive a larger and cleaner interior but also perform as well or better than my old $50 case.

Before I purchase the HAF XM I have been looking at the motherboard temps on my old case at the BIOS everyday and everynight, it is always around 19-21 degrees Celsius. Today I looked at my HAF XM the temps goes to 27 degrees which is a large difference from the 20 and 21 degrees. Yesterday it hit 28 degrees even though the ambient temp are the same (winter here).

You must understand that, the bigger the case, the harder it is to cool it down.

 

I strongly believe that you had better temperatures in your old case because it was smaller and easier to cool it down.

You can compare it to a room. Is it easier to cool down a big room or a small room? Some concepts are common to both.

 

If you don't need to fit a lotta stuff, there's no meaning in buying something huge. I believe this must be the case(pun) here, unless you have a lotta stuff in there, then my bad.

 

As @austin541 already said, you should not worry because your temps are not high at all.

Try different layouts, try negative vs. positive pressure. A lotta people are negative pressure boys and others are positive pressure boys. I believe that it depends on so much more than just having negative/positive pressure. You might live at a hot place, dusty place, the case is inside a desk with not much ventilation, etc, etc - everything matters.

 

Change something on your layout, test it for a couple of hours. Repeat that until you think you have found the best temperatures.

If I had to try a new layout, it would be: 2x140mm front intake, 1x140mm rear exhaust and 2x140mm top exhaust, controlling the top exhaust fans' RPM so that you have positive pressure whilst idle and negative when under load.

Also, just because you have 7 fans, it doesn't mean you must use them all. Number of fans does not always mean better cooling. 

 

Good luck.
