Memory Heatsink - RAM Cooling

[katzdvd]

Well... I was browsing the shelves in my local pc shop the other day & was looking over the cooling devices, & came across Memory Heatsinks/RAM Cooling.

Does anyone use these, are they needed or are they just a gimmick to clean my wallet more?

all good ram already comes with heatsinks installed, if you aren't overclocking your ram(increasing voltages?) and have adequate case cooling, it's not needed

the guy who inspired me with my overclock built a small fan blowing down on his ram

what do you think of the "slot exhaust fans"? seems to me that since hot air rises, that if you used one of these,

it would simply pull the "cooler" intake air from the front of the case & exhaust it before it really got a chance to circulate properly...

I use case fans and the design of airflow is a very advanced science,
thermadynamics/heat transfer? Each enclosure takes something different.

My last project(to cool an overheating cpu) involved adding 2 case fans
to cope with summer heat in an unairconditioned room, noisy as heck.
But it stopped the computer from crashing.

noisy as heck

yeah, thats what I don't want... I overclocked a Celeron a couple of years ago & had 6 fans total, plus the one on the vid. card...very noisy

I saw a site where a guy built "ductwork" in his case to direct the airflow from the intake & route it directly to the CPU & other "hot" areas.

It looked like a neat idea, but I never got motivated enough to do it.

I may one day though

My overclock(40%) is handled beautifully by a TT large heatsinkfan(whisper/low rpm) and a 120mm case fan exhausting high rear, can't even hear the computer running.

case fan exhausting high rear

I thought about installing something like that, but was not sure about the noise levels of the different fans;

Is there a general rule to look for in determining which are quiet fans?

[Chewy]

larger lower rpm ones are quieter, high cfm/low dB
