The purpose of the hole is the equalize the air pressure. It's not a problem as long as it's not airtight, even if you block the hole with something.
You guys can't see in the pic. Actually, only about 30% of the foam is under/above the drive just enough to support. This will allow some airflow, reducing the HDD temp up to 5C.
Pretty decent mod Chai! I was planning to do a similar thing with my system. Since I don't have enough space to do elastic suspension, gonna have to use some foam as well
But do remember dun leave the drive hanging without any point touching the chassis. Need some grounding path to disperse ESD ...
The power cable is not sufficient for grounding? Actually, there's no point of contact with the casing at all, since that's the source of the noise/vibration.
Usually design recommendation to have chassis grounding point other then power cable .. maybe just a wire or aluminum foil touching the drive to chassis.
will disperse ESD when u touches it. .. Is ok la IMO just recommendation as all good chassis wud take that into consideration for any unlikely event high ESD n such
This is the mod needed the change the PSU. First I removed the fan from the connector of course. Then you need the take out the 2-pin fan connector holder on the PSU using a flat head screw driver. Once you take out the fan header, you can use almost any type of fan connector, 2-pin, 3-pin, or even the new Intel 4-pin if you want to!
It's not that simple to find the right PSU fan. It should be medium to high speed fan, to make sure the fan will still spin properly at 3-4V, that's the usual fan speed when the PSU is at low load. It's best to test the fan at low voltage before putting it in. And be very careful with PSU. It should be properly discharged first before opening. If not, don't blame me if you don't get to post here again!
