heat pipe?

Snuffy09
Whats the CPU accessory called that tunnels hot air directly off the fan of the processor to your case fan. I have seen these before I just forget what they are called now that I may need one. They look like condoms with the end cut off Haha

    In the majority of cases, it would appear that the implementation of one of these contraptions is going to contravene the existing airflow.

    My gaming rig has a punch-drilled hole in the side casing just where a straight version of one of these ducts would sit - directly in line with my CPU. However since the duct is designed to carry air OUT, it would be constantly fighting with the CPU heatsink fan which is drawing air IN to flood the heatsink and convect the heat away from (through) the heatsink fins directly 'below' it.

    Or have I got it wrong ?

    Or is it supposed to be a method of supplying the heatsink fan with an 'uninterrupted flow' of incoming air ?

    From my understanding it supposed to be a method of supplying the heatsink fan with an 'uninterrupted flow' of cooler incoming air. The extractor fans are supposed to get rid of the heated air out the rear of the case.

    my processor has a heatsink and fan, the fan blows air away from the processor. my case fan also blows air out of my tower. So i figured i would connect the 2 with this device for faster heat removal.

    Will this heat duct work on a AMD Athlon X2? It doesnt say much in the details.

    Mmm - are you absolutely CERTAIN it's lifting the air AWAY from the processor?

    I'd have thought it would've BLOWN the air into the heatsink, to cool it down.

    after market heat sinks and fans that do this, but its non-standard (I ahve all so seena few that blew air sideways across the heat sink...).
    Pulling air down and onto the cpu heat sink also forces air to circulate around the memory and chip set better then the reverse process.
    But in any decent case design, heat should not be an issue unless overclocking.

    CPU fan should **** hot air away from the CPU and the case fan takes that air out. I fyou have a case with 2 or more fans you can use a fan for intake.

    I am not disagreeing with you it is just what I have grown to understand about it.

    How can you tell? Tie streamers to the fan grill like they do on the A/Cs at SEARS?

    Let the CPU heatsink fan spin up, then let the strip of paper brush gently against the spinning fan and see which way it gets pushed, thereby indicating the rotation.

    Power down, remembering which way the fan was turning and examine the fan blades.

    Turning whichever way it was turning, would that shape of blade PULL or PUSH the air (INTO or OUT OF the heatsink)... :)

    Which may be different than most since there is no fan above the CPU.

    My Dell Precision 470 has dual Xeon processors. Each processor has a heat sink - fairly tall. Above each heat sink is a heat duct - rectangular in shape. The ducts comes up from the heatsink and then does a 90 degree turn to end at the back of the case, same side as the connectors etc. The fans are at the back, so they suck the warm air off the heat sinks and **** it out the back.

    Some are just a simple finned aluminum plate that is stuck on top of the CPU with a little heat sink compound in between to help conduct the heat. Some are elongated to carry the heat to an area where a fan can **** across it and located near a vent duct, most often in the confining spaces on a laptop. They are called a heat PIPE.
