hi

we purchased 6 servers from dell india.

we are facing a severe heating issue on top of the chassis above the raid card with all these 6 servers.

server configuration

R420 - single hexcore processor 2.2 ghz, 32gb ram

4 X 600 gb 15000 rpm drives
(configured as 2 drives in raid 1 + 2 drives in raid 1)

these servers are placed in a datacenter -- temperature is around 18 deg C

we are facing a severe heating issue at the on top of the chasiss just above the raid controller

when the servers are placed one above the other like they are normally placed in a datacenter the servers heat up between 50.4 - 57 deg celcius

dell support has changed motherboard, raid card , power supply etc of one of the above servers which is non-production (heating to 50.4 deg celcius) but the issue is not resolved

On closer examination of the raid controller card i noted that the fins of the heatsink on top of the raid controller card --  instead of being parallel to the airflow is actually perpendicular to the air flow and is actually trapping all the heat

the same card in a R620 server has the heatsink fins parallel to the air flow which remains cool

has anybody else in this forum noted this and are facing such a heating issue ?

could you please check this and let me know the resolution to this problem

can the heatsink be turned around by 90 degrees so that the fins of the heat sink are parallel to the airflow ?

thanks for your help
