hi ya manel

if your systems have "health monitoring"...
check your bios to see what it thinks is your
current system temp and cpu temp...

you're cpu reliability/performance goes down
by 1/2  for every 10 degree C 
	- ie  if it would have lasted 5 more years...
	( starting temp is "normal/nominal  temp" as provided
	( by intel or amd that they provide a cpu warranty for 5 years
	- if temp went up another 10deg C... its now 2.5 yrs
	- it temp went up 20 degree.... its now 1.25yrs...
	- or some silly guidelines like that..

to test if the ambient temperature is too high...
	- add a regular fan and blow air on it...

	- if the cpu temp drops significantly...
	than its too hot in the room

max cpu temp...

-- add lm_sensors to your "distro" to read the cpu temp
   and if it gets too high... shutdown the server 
   or at least dont do heavy computations on it
	- add more fans ... and better air flow...

c ya
alvin .. more specs ...
