i've seen the casing itself, and yep the airflow is bad......

1x 120mm intake and 2x 120mm exhaust doesnt make the air flow good...


there's some detailed pics of the casing over here : http://www.bjorn3d.com/read.php?cID=810&pageID=1629


Problems :

- the stock fan is a low cfm fan
- the front 120mm fan doesnt suck in any cool air efficient coz the path is blocked by the HDD cage, front grill, and the worst part is the front filter that filter air.......
- just imagine you have got the same fan, 1 intake and 3 exhaust including the the 2x rear and the PSU, the casing is choking for fresh air dude.....

Solution :

- increase the intake capacity by adding a hole at the side panel, then make an air duct direct to your TT heatsink
- add a 120mm fan on the side panel, 2x 120mm better still...
- ask uncle ianho to make a big lubang on the base of the casing and install fan there...

hope that helps


over casing pics....see here, the HDD casing is blocking the airflow from the front intake



these are the pics of the intake fan.....
the blow side of the intake fan is blocked by the HDD cage, intake is blocked by the filter, and there duct from the front panel is also blocking the airflow.





rear part of the casing is okay because of the 2x 120mm intakes



usually i dont want to tembak here and there coz you know you spend so much on the casing, then someone say negative things about it......but if you're serious about the airflow problem, i hope you'll accept my suggestion.....k

AFAIK, a fan on the sidepanel covering the CPU and GPU area helps the most even you've got a good intake....

i went to this forummer's place before, same casing as yours....his Opteron 170 also get the same problem, have to open up the side panel and the temp drop a lot !
then the front intake filter must be clean very often coz if it's dusty, the airflow is like totally zero....

regarding changing the front intake, i suggest you to remove the filter, cut the mesh, remove the plastic bracket from the front......that will actually work better than replacing the fan itself coz a filter that near to a fan will simply kill the airflow....

just imagine you put on a surgical mask, it's difficult to breath right ?
the same apply for the fan also

sometimes, people get offended easily you know.........and sometimes i'm really good at spotting all the weaknesses

just remember this :

Good airflow is equals to free flow and cooling on the hot spot, meaning no obstruction for the intake the exhaust and active cooling on the hottest spot, which is near the CPU, GPU and mofset area.....

i built some kind of wind tunnel last time, with motors to monitor the airflow,not really accurate but it can give whether air is moving faster or slower and stuff like that....

i think it's got related with fluid mechanics stuff.......i tested that if you duct the intake for a fan to a specific length, the pressure is more, then putting a grill or anything which will distort the direction of flow, like grills and things like that, the airflow will drop a lot....the same applies for exhaust......

yalor.......that's why i dont want so spoilt the fun....knowing that you spent so much on a casing that doesnt have good airflow is heartbreaking isnt it.....

1. i tried that also with that forummer with Opty 170......works for a while only coz once the bay door is shut tight, it's really limiting airflow again coz the holes are really small.......

it's the same old airflow problem that every casing has, especially those with bay doors......


2. good idea also.....but why not just make a duct from side panel to the heatsink area right ?
that fan is claimed to be at 18dB

since opening side panel will allow around 10°C drop.....

this will only work if you leave the bay door open....if you close the bay door, then it's meaningless

can you hear your neighbour doing 'project' at night ?

woooww.....that's like laser cut quality.........



glad that works for ya...
