Volcano 6cu

[I0's]

Hello
i have a volcano 6cu and i have noticed that the air blows into the HSF instead of sucking it out, should it be the other way around??? should i flip the fan?? has any 1 tried it??

[bushmaster]

It is supposed to blow cool air down into the heatsink.

Sure have tried it :D

Read my posts over on 2cpu.com and decide for yourself...

I'd definitely recommend flipping the fan over on this heatsink..!
Just do it carefully if you don't remove the heatsink first; don't come back saying that you're chipped your cpu core please :)

but its more like blowing heat into the heatsink
btw, i should mention this too
since i have a old case my power supply does not go on top but vertically on the left side, that means my psu fan and HSF (volcano 6cu fan) is right next to each other barly any space (back to back), that means my psu fan sucks air and HSF fan blows air, that worrys me, any comments??
due to this condition should i flip my HSF fan so that it sucks air??

Can you post a pic (time for the digital camera or webcam!) so we can see for ourselves. This consulting service is free, but we need solid info to work on :)

:D dont have none, sorry i cannot get a pic
i hope this helps

eFrisky??? any ideas??

If you flip the fan on the heatsink over, is it possible for you to duct the warm air being sucked away from the heatsink, towards the fan on the PSU? This should draw the warm air straight out through the PSU.

If that's not possible, then can you keep the heatsink fan as it is (blowing onto heatink) and try to duct the warm air from the heatsink towards the fan on the PSU.

It's basically a good idea to expel that warm air from the heatsink straight out of the case, rather than have it "trapped" inside the case.

Thats not a good set-up. The fan on the antec psu is pulling air into itself, and at the same time the fan on the heatsink is pulling air into itself. Now if those 2 fans are back to back, essentially they could be cancelling each other out and causing in-sufficient air flow to both components. At this point my suggestion would be to get a decent size case so that you can mount your psu and mobo in a more civilized manner.
I'm going to guess that you are using the old case that came with with a pre-built comp, ie; dell, HP, gateway, etc. Most of those cases are very proprietary as far as hardware goes.
This case (http://www.xpcgear.com/ansxtowserat.html) is what I use to build boxes with as it is very well constructed and provides plenty of room for keeping your goodies cool.
Also how many other fans do you have in your current case?. I like to see at least 2 independent fans both pulling in fresh cool air and expelling the warm air.

eFrisky: i think i am going to flip the HSF fan so that the PSU fans sucks out the warm air, that was its gonna be like the pic in the URL (u posted b4) except without the PVC pipe.

bushmaster: yes, the case came with my pre-built comp when i was a newbie from a local comp. store, but since then i have upgraded alot (almost everything), i know i need a bigger case but :( . btw my air ventilation is kinda bad in my comp, i do have one 80mm fan which should suck in air, but i turned it off since it was making too much noise and did not find it useful caz of the nature of the case, for the outlet of air well the psu fan is 1 and i have opened one side of my case so air can go in and out freely.

that the main reason y i was worried, just wanted to know if there is any use in reversing the HSF fan, as my first option
btw i do get temp at 40C at ideal (with CoolerXp running) and around 55-60C at load

Reverse the fan and monitor any temp changes. My guess is you will just get a hotter reading. If you don't like the noise from your fans well that is another problem , it sounds like you need a couple outtake fans on top of your case. Might be more economical to get a new case, as suggested.

Try to create a negative air pressure situation inside your case.

[bushmaster]

If you don't remedy the situation, wether or not the side of the case is off you still have a cancelling effect at work there thats going to severly shorten the life of your psu and cpu.
Either you must have equal in/out ventilation or take a house fan and blow it into the open case. Either way you're going to have to live with some noise from some sort of fans or not have a computer eventually.
Remember your psu is like a box within a box. if you dont have air flowing through the psu it will become a little oven.

:eek: :eek: :eek:

i will first reverse my HSF fan and then c what results i get

I wanted to ask you a question.

Does your processor run at 100% usage when you have CoolerXP running? Mine does. It slows things down quite a bit. Doesn't seem like this should be normal.
I like using CoolerXP, but can't use it if it uses 100% processor time.

yes it does run at 100% usage, but i dont feel it slowing me down. If u are running other programs then CoolerXp gives priority to other programs, that way it does not slow u down.
I have noticed the above and dont have concrete proof to back me up, but i think thats how it works caz i dont really feel it slowing me down, btw i would rather wait 10's of a sec than let the heat slowing bake my cpu :D

The easiest way to get a huge decrease in temps would be to make a duct coming in from the side to the HSF, and keep the fan blowing on the heatsink. This will drop temps at least 10C because the heatsink will be getting cool air from outside the case, it won't have to work against the psu fans, and it won't recirculate its own hot air.

All you need is a 3" holesaw (about $8) and some cardboard, wood or plastic. :)

i did reverse my Volcano 6cu fan, now its 1-5C COOLER than b4 at ideal
and 5-10C cooler at max :D

[Giblet Plus!]

Make yourself a duct and it would be another 5-10C cooler. You could really overclock it then. :)
