Okay I got my Scythe Kama Bay installed. Sadly it hits the included crappy dust filter so it is very loud... 😡
EDIT: ^^Fixed that issue by cutting off a little bit of the filter.
I couldn't get it into the bottom three 5.25" drive bays since the bottom one has a 5.25" to 3.5" drive bay adapter which can't be removed, and it is in the way.
Cools better than my Antec 300. My ATCS 840 has 11 fans, while my Antec 300 has 5 and the ATCS is much quieter. CPU idles at 32-35 degrees, GTX 260 idles at 42-43 (still waiting on 4 new CM R4 series 90 CFM fans, backordered), 9600GT idles at 44, and my HDD idles at 28-31 degrees Celsius. Pretty good temps.
Advanced Thermal Cooling System 840
This is why I want it in the bottom 3. Look at the 5.25" bay, a modded 120mm fan. Oh well, no big deal since it still gets the air from the kama bay, just not as good.
Here is the airflow setup.
I ordered a Prolimatech Megahalems and extra fan clips today, and will be ordering two blue LED CM R4 series 120mm fans from microcenter soon. I'll get two Scythe Slipstream 120mm fans, they're black and I'm getting two 1900 RPM/110 CFM models.Two non LED CM R4 series fans are coming tomorrow.
