Thermaltake Ducting Mod

I did a search on AOA but didn't get any answers, so I thought I'd post here:

I have a Swiftech MC462 that I'm very happy with... Keeps my o/c 2400+ below 40C at rest, and no higher than 45C at full. But I just stumbled upon this item from Thermaltake that some people have said they've added to swiftech HS - it's cheap enough, but would it actually make a difference?

Anyone added one and seen a temperature drop?

I may be wrong, but I don't think it is worth your money...

AFAIK, ducted cooling for a CPU works well when the duct is grabbing air from outside of the PC. A duct that sucks air from the inside of the box is next to useless, it's only a long "neck" on the CPU's HSF.

If you made a duct that draws air from the cooler exterior of the case that would mate up with this Thermaltake "one half of a duct," THEN you would see the benefit. It can be substantial.

After reading the info at Thermaltake, yes you would get improved cooling using this device. How much? Probably not enough for the investment. Mate this puppy up with a duct that's open to the outside of the case. Better, save the money and build the duct yourself. All you need to do is cut a hole for an 80mm fan in the left cover of your case. The duct can be built of cardboard and duct tape. Dryer exhaust air hose will work. Heavy copper water pipe, cut, welded and fitted to perfection is insisted upon by some perfectionists.

Hey, to loose 7 - 10 db of noise it may be worth it. It also allows for a good start to add some additional duct to, to get "out of the box" air in there. Attaching a duct has always been a problem for me. This gives you a good start. By it's self I see little or no use for it aside from the noise reduction claimed in the conclusion..

One of the reasons Dell machines are so quiet is that they use ducted fans and shrouds. I should know, I've recently taken apart 3-4 of them so I can reuse the cases. I love the things because they're so quiet. BTW, I mean the old beige cases and not the new funky opens on a hinge black monstrosities that weigh 75 lbs.

Thanks for the responses, everyone...

As far as noise reduction, my system already sounds like a vacuum cleaner, so I doubt I'll get much help. Front intake fan, two side fans, two rear and on top exhaust fan (not counting my CPU and video card). And like you guys said, I probably wouldn't see a big temp drop unless I made a full exhaust duct...

Thanks for the help, I think I'll save my pennies for that new video card I've been wanting

I admire the guy who made this, this is a proper duct:

I really like the sound of this idea but i have one quesiton..
If you have a full duct to the outside of the case do u still only use the one fan and take it off the heatsink and place it at the entrance of hte duct or do u keep the fan on the heatsink and add another one on the end of hte duct?
(My lack of physics knowledge has probly jus been shown up - A* GCSE physics uve gotta love the UK education system.

I wouldnt use one fan myself.

I prefer fans blwoing over the fins not drawing off the fins. Requires less poressure to hget rid of the heat that way.
