A poll about your power supplies

pHaestus · 05-14-2005, 10:19 PM

What does the airflow/cooling of your PSU look like? I have a reason for asking; I started putting together the Procooling wcing system test bench today and noticed that there's considerable chance for the radiator in the top of the case to interact with the psu. I don't think this is unique to my case. Anyway answer the poll and then let's talk about this a bit (I'll put up a picture too later).

maxSaleen · 05-14-2005, 10:31 PM

Mine (OCZ Modstream 520, I'm too lazy to sleeve cables) has a 12cm low speed fan on the bottom. It moves a surprising amount of air. I can't comment as to how it would effect an internally mounted radiator, as mine (BIP 3) is mounted externally via Radbox.

I wonder how well a PA160 would do hooked up to such a PSU (mounted via shroud directly to the PSU fan so that air is being sucked through the PA160). A one fan system would be sweet.

antec trupower for me
a 430w and 350w
i had to check that they were on when i 1st bougtht 'em
the fan dongle is nice, too

thanks max

RaptorRaider · 05-15-2005, 05:55 AM

Other: 80mm fan at rear and 80mm fan at front.

I have two LC (Levicom i guess) 300w , each with a low dB 80 fan on the rear, and plenty of openings.
Probably could use some extra airflow (fans) thou...

80 mm fan at front for me (on all three supplies

).

HammerSandwich · 05-15-2005, 02:11 PM

My WC Genie has fairly unusual airflow. When I WCed it, the Seasonic Super Silencer (single 80mm) started ramping its fan thanks to the warm intake air. To fix this, I divided the top and bottom sections of the case and removed the 92mm case fan in the top section. Now the lower half has a 120 pulling air through the intake, HC, and across the mobo. In the top, the HD exhaust hole is now an intake for the HD and PSU. Works well.

I recently swapped the PSU fan to an L1A, which helped noise and (apparently) provides adequate cooling.

JSimmons · 05-18-2005, 05:39 AM

Thermaltake - 120mm top, 80mm back
OCZ - 120mm top

maxSaleen · 05-18-2005, 08:19 AM

Let's establish some terminology.

I consider the exhaust of the power supply (where the AC in is) to be the BACK
I consider the side opposite the BACK to be the FRONT
I consider the side, as intended by ATX standards, facing the top of the case to be the TOP
I consider the side, as intended by ATX standards, facing the bottom of the case the BOTTOM

This ok with everyone? I just presented this to simplify things.

JSimmons · 05-18-2005, 08:34 AM

I obviously conform to standard terminology.

GlassMan · 05-18-2005, 09:36 AM

2x80mm, front and rear. Inside fan is the workhorse, outside fan only runs under high load.

Why the sudden interest in psu fans? Planning a 120mm radiator to bolt to the bottom of the psu?

jaydee · 05-18-2005, 10:56 AM

80mm on bottom (right above CPU cooler) and 80mm rear (out the back of the case). Generic brand came with case.

I have the same power supply... and use an external radbox as well...
having the cables ready with sleeves is nice

ToasterIQ2000 · 05-20-2005, 11:14 PM

No fans:
Power supplies (which are transformers, yes ... ? ) in transformer oil, in boxes with at least one copper side that is water cooled.

Silent, yes. < 50% success rate, that's me. Obsoleteed by new commodity fanless PSUs, appears so.

KnightElite · 05-21-2005, 02:12 PM

I'm using the Thermaltake PurePower 420 and 480W supplies. Both with fans on the bottom and the back, though I believe the 420 has an 80mm on the bottom and the 480 has a 120mm...

killernoodle · 05-22-2005, 12:28 AM

I have a True 430 and it powers all my stuff nicely. This includes 4 hard drives. Nice and quiet too, never had a single problem with it.

plywood99 · 05-23-2005, 09:21 PM

A Seasonic 350 continuos watts, custom made for for Artic Cooling Silentium T2 case. Uses two 80mm fans mounted externally.

Voodoo Rufus · 05-24-2005, 06:16 PM

Sparkle 350W with a Panaflo 80L that I vary from 7-12V depending on the weather and air temp coming out.

Hansfragger · 05-24-2005, 07:57 PM

PC Power and Cooling 510 Deluxe. A single 3-bladed 80MM rear exhaust fan. The noise from the 510 is not only irritatingly loud(34 to 44DB), but has a really annoying characteristic that is hard to describe. Kind of like a rubber band being flicked really fast. Right now I have a DD DDC pump, Swiftech NB HS fan, 2-120MM case fans(one SilenX@14db and one stock LianLi@30db) and 2-120MM external rad fans(two enermax@26db)- and the power supply drowns them all out. My wife left the room after about an hour saying "The noise was really irritating". This leaves me with 2 options-super glue some earphones on or void my 5 year warranty by replacing the fan with a quieter, equivalent cfm model. It appears from pictures and talking to people that PC P+C uses a proprietary fan connector that will have to be cut and soldered onto the replacement fan. I have already found a higher cfm, substantially quieter fan-just can't find anyone who sells it yet. My 2 cents. There is nothing near the fan, just the fan bearings and blades making all that racket. I find it interesting that the majority of reviews of this power supply make no mention of the loudness or irritating characteristic of the fan. One review even said-The fan is near silent at low RPM but a little loud at high rpm.

dogbait · 06-03-2005, 09:25 PM

Make sure the drive bay opposite the psu is unobstructed to allow cool air into your PC Power and Cooling PSU. Its fan will run at a lower speed.
In addition sticking a fan (using cable ties) in front of the intake grill on the PSU helps.

Otherwise watercool it

who knew Welders were at these voltages?!

You could run some serious TECs of of that though!

Ive got one 80mm in the back as customary and one in the front pushing air through, i think this works welll although it makes wiring a tad tougher.
