Hey guys,i have the old CM690 not the CM690 II yeah.
I was wondering my hard drives all are running at 40C.
Why is that arh? I have 3 fans blowing out with CFM 80+ and 3 fans blowing in.
One front the front,one from below and one from the rear for intake
Exhaust is one from the back and both from the top.

The hard drive seems to be able to blow i mean i can feel the air blowing through the drives.
Problem is why is it still so hot.
Previously i was using TJ07 and the drives were around 32C only.
Then when i change back to my old casing,it became this way quite high.

Thanks guys is there any mod i can do to fix this up?Cheers

normal for CM690 i think.
using the casing too, got 4 HDD at the bay.
120mm pulling cool air in. 140mm suck hot air out.
avg temp is 40C too

Wahhh~!!! 40C? My cap ayam casing only 31C top...i think the HDD bay position cause it, no? try turn the bay facing the front intake fan...

increase the gap btwn hdd? normally around 35c during gaming...maybe try to clear up the hdd area (cable) to get better air flow...

@dan137
I tried hmm it seems that the HDD is quite hot maybe it's because all in one bay?..
@kherel77
Yeah,cap ayam one better air flow for the HDD side mah i mean it faces another side.
The front bay is already a intake >_<
@Iamjunrong
Hey i just increased the gap between HDD,seems to be normal already but still one of the HDD running at 39C, i guess the heat is accumulated around that area.
Managed to remove one drive from the bay though.
