Hi folks,

 

I'll be upgrading to a norco-4224 in a couple of weeks.

The new chassis needs to go into another place, where it will be more exposed to dust

(eco-green tumble-dryer in the same room...which is a cold device...so no heat or humidity problem, but a dust problem).

The case will be mounted well above ground (4-5ft).

I have G4 air-filter mats already at my disposal...but I am seeking your advice on how to mount them.

 

The biggest problem, as I see it, are the hot-swap bays being the intake.

Is it a feasible option to swap for more powerful vents and mount them in reverse and  just cover the vent intakes?

 

thanks in advance for your help and input.

 

regards,

        Ford

Hey ford,  what did you do? I am also thinking of reversing the airflow

 

I don't know that you would want to reverse the airflow of a 4224.

 

instead of cooling the drives, you would be heating the drives. the CPU, RAM and especially the HBA/RAID cards will be generating a lot of heat. this heat would then be pushed over the drives. (When I put my hand behind my norco's, the air is very warm.)

 

also, the motherboard section of the 4224 is normally positive pressure section. buy reversing the airflow, you might not get enough air though it.

 

you would also need a PSU that is normally passive cooled like a seasonic. the PSU would cause a vortex pulling your air in circles around and and around.

 

 

I would recommend finding a way to mount some sort of air filter to the front of the 4224.

A buddy of mine build a server rack out of 2x4's and leftover plywood and then made a front bracket that held standard furnace air filters..

 

keep in mind using filters will reduce the airflow and cause warmer temps. usually the cooler basement offsets this issue. but keep in mind higher RPM/power/CFM fans might be needed. the stock fans "should" be fine for this.

 

I used to keep my servers in the basement also. I had an air purifier by my server rack. unfortunately it did not get a lot of my dusty air. As part of my monthly maintenance (more like every few months with my schedule), I had to blow my servers out with compressed air. I just used an air compressor cranked down to low PSI with a moisture trap on it.

... thanks for bumping that thread back upwards 

 

I haven't made any progress, since shortly after I heard a lot of complaints regarding

bad backplanes with these cases...so I am still running my old case.

 

As it seems there is not much of an alternative around, with the same bang for the buck.

So I was just about to order next week.

 

Meanwhile, I gave the dust and cooling problem some more thoughts and came to the same conclusions, as laid out by Johnm.

I have an active airflow system in the house and this uses filters with a cardboard frame. I might as well construct such a frame

to cover the case from the front. You can slide it on and make it fit tight with some insulator stripes, like these: http://www.tesa.com/consumer/tesamoll

 

As usual,  a lot of very useful info.

 

Thank you both
