Power Supply Question!

[elfnumber1]

I just purchased this case (with included PSU) from Directron: here

I realized that the PSU gets really hot after normal use and also that the fan doesn't really suck in too much air. I have some 6 panaflo's sitting around that need to be used, would the panaflo's do better than this current fan (for PSU)?

I have concerns because there is no rating on the PSU for the fan and I don't want to take this PSU apart 'less I know the panaflo would cool it better and quiter. The link should have the specs of the PSU, but I'm not too sure about the fan stuff. LMK.

thanks,

help bump please!

Bump for ya ^^

Thanks but do you know how to help me? HELP PLEASE?

well..i'd give the panaflo a shot as the pics of that psu didn't exactly exude quality to me...but playing inside a psu is quite dangerous
if you can afford it i'd go for a better psu instead of messing with that one
a dual fan antec or enermax would improve your cooling and also quite possibly your overall system stability
most cases are sold with the cheapest psu they can get away with putting in there

but playing inside a psu is quite dangerous

It can be if you are not careful. I think the best way to go about replacing a psu fan is to remove the current fan entirely. Then, instead of connecting the new fan to the psu circuits just run the cable out the botton of the psu and hook it into a molex. That way you don't have to deal with all the problems associated with messing around with the psu.

just don't lick yur fingers and start rubbing up on capacitors
or have it plugged in while yur trying to work in it
ohhh yeah and don't put it in water or or something

if you follow those three rules then yur pretty much not gonna get shocked

ohhh yeah and if you absolutely must get shocked try to only have one hand touching something
don't want one hand on a grounded out surface and the other touching an exposed wire
it'll go right through your heart, and if yur lucky, stop it on the spot
heh heh

i wanna see some sparks and stuff
keep up the good work

 

[elfnumber1]

hey soulkeeper, i'll be sure to be touching you with my other hand if that shock does go through my heart. =)

anyhow, thanks for the help, seems like it'd be better worth my efforts, safety, and time if i just spend the money to get a better PSU. suck, this case sucks and so does it's PSU.

thanks again!

Having a 'quiet pc' is all the rage these days. PC Power Supply vendors have responded by supplying 'quiet' PC Power Supplies.

Pretty easy to do - just install low-rpm low-flow fans in these PC Power Supplies. That's what Antec is doing. I have a Leadman PowMax 500 watt PS that's quiet by virtue of two 'quiet' 2900 rpm fans.

When I installed the PowMax in a negative-pressure case fan configuration, I had practically zero-flow through the Power Supply. It simply couldn't compete with two 40 cfm fans extracting from the case. I had to reconfigure the case fans for positive-pressure to restore air flow through the PowMax PS.

Three things you can do:
1. Make sure that you have positive air pressure in your case (more intake pressure than extraction).
2. Replace the PS fan(s) with higher-flow fans (not as 'quiet').
3. Remove the cage from the PS to reduce air-flow restriction in the PS.

I did steps 2 and 3 with an Antec 300W PS and it ran cool and reduced case and PS temps nicely, with no frequency-emission problems whatsoever. Next time I'm bored, I'll probably modify the PowMax similarly.

With the current string of 95-degree days here, I'm a lot more interested in 'cool' than 'quiet'.

Hope this helps!

dunkster,

Thanks for all the advice. I'd like to clarify a few things from your three things I could do:

1. Make sure that you have positive air pressure in your case (more intake pressure than extraction).
2. Replace the PS fan(s) with higher-flow fans (not as 'quiet').
3. Remove the cage from the PS to reduce air-flow restriction in the PS.

1a. what does it mean to have positive air pressure? this PSU has only 1 fan and pushes air into the PSU and thus into the case. my enermax has two fans (1 in which pulls air from case out through PSU and then 1 in which pulls that air out of case - or maybe it's the other way around)
2a. when replacing a fan in the PSU, does it matter what the different voltages or currents are? or would almost any fan (of the same dimensions) work in a PSU considering it would plug in the same place?
3a. that seems fair enough

I'm considering either or:

Returning this entire case, I am not impressed one bit or putting in my enermax from my other case. If anyone has any further advice maybe you could also direct me to which way I should go (return or replace PSU). Thanks again!
