Interesting Cooling Idea

[MoFunk]

Anyone ever tried something like this? http://www.case-mod.com/store/product_info.php?cPath=28_31&products_id=508

 

[Technonut]

I have seen it before, but did not know it was available. Thanks. I think that I will try one with an 80-92mm adapter on my MCX4000.

 

[MoFunk]

If you do get it, can you post your results? I am very curious about this. I have been looking for a good cooling concept and may give it a try if it works. I have an SK-7 at the moment so would have to get a new HS since mine uses clips and this one screws onto the HS.

 

[Technonut]

Sure... I will post results when it arrives. I already have the 80-92mm adapter.. $7.99 is not bad for the duct. It should work well to direct airflow over my MCX4000 and eliminate the "dead zone".

 

[MoFunk]

Thanks. Looking forward to that!

now this ive gotta see!

I've seen it before and have thought about trying it. The theory makes sense. I'd have the fan in the opposite direction though.

 

[acemcmac]

meh, i don't see the point... i have a swiftech 4000 as well, but i bought a TMD for it from crazypc.com. it's supposed to reduce the dead zone in the center, but I'm not really concerned about it. So long as the 2.4b I'm getting this week from a friend of mine coupled with an i865 when they come out can take it over 3ghz, I really don't care.

any thoughts?

Why couldn't you just clamp the adapter thing on, and screw the fan to the adapter? (I have an SK-7 too)

They are out. I have an MSI 865PE on the way from Newegg ($105). They also now have the Abit Springdale. That TMD looks neat, but 38dB is too loud foe me. Good choice on the HS.

To me it does not look as though the adapter has any place for those wire clips to hold onto. But maybe with some shorter wire clips maybe. i dunno, that is just what it looks like to me. I would consider making the purchase and taking the rish, once I can see some result in saying that it is worth a try.

The little "nubs" on the clamps just sit in the screw holes...

Just how effective is this?

 

[smahoney]

I use a 120mm to 80mm with an Alpah 8942 and a Titan Aluminum 120mm fan - The additional 25mm from the adapter helps smooth the air and I get 1-2C better than I did when trying a Tornado while getting less than 32dBA from the fan.

It is the same concept as a longer throttle body in a car. Very efffective with high RPM fans.

I dunno, how well would that work with a Panaflo L1A that already has low CF? It's tempting though, assuming my single prong HSF can hold it.

Hey! Maybe two of those could form a curve to one of the 80mm fan outlets on my Chieftec Dragon case. Hmmm....

I was sort of thinking the same thing, adding an extra duct to the outside of the case so you are sucking in pure outside air and not warmer in the case air. This could be interesting.
/me going to home depot to look for some ducting material.

The problem I forsee with this is that if the fan is pointing towards the general direction of what is usually the 80mm exhaust, then the conventional setup would mean that the fans are fighting over air. It might create the need to change setups around a bit.

 

[oldfart]

Yup. The fan should be pulling hot air from the HS where it would then be pulled out of the case by the rear exhaust fan.

Or

The rear case fan should be an intake and the CPU fan would blow the cool air from the intake fan down towards the CPU.

I prefer the first methid. I dont like the idea of the hot air off the CPU being blown out the base of the HS towards the NB, ram and mobo components. Just MHO.

Yeah, but most heatsinks prefer air blowing onto them. If you dip some degrees with the duct, you'd probably add back that much with pulling air off the heatsink. Its kind of a toss up atm. Long day at college, exams next month so I cant think properly.

 

[oldfart]

Its not the CPU temp I was talking about. Its how hot other things around the CPU get from blowing the hot air off the bottom of the CPU HS towards mobo components. I'd rather pull cool case air from the bottom of the HS, then exhast the hot air out of the case via the rear exhaust fan.

I received the TT Ducting Mod, but my 80-92mm adapter does not fit it properly without air gaps. I am going shopping for an adapter that will work. In the meantime, I have found a short review on the Ducting Mod Here for your viewing pleasure...

 

[MoFunk]

That is interesting that the cpu temp went down a touch and the other temps went up. According to those numbers his HD temp went up 20c. But overall it looks to help a bit, not much, but enough to help. Let us know how the search goes Technonut.

 

[Jeff7181]

I don't think this contraption is meant to "suck" air off the CPU and blow it out the back... the description of it tells exactly what it's meant to do... with a fan mounted directly on the heatsink, the center of the heatsink (where the core is located and producing the greatest concentration of heat) doesn't get much air flow... it's in the center of the tornado so to speak.
This part, moves the fan away from the heatsink, and has the bend to distribute air more evenly over the heatsink's fins.
As far as fighting the rear case fans for air, just turn it so the open end faces the front of the computer.

 

[lookin4dlz]

If you're running an Intel CPU, don't waste your time as they don't run hot enough to make this worthwhile. I used a duct to vent the air to the outside of the case with a fan on the hs and one on the case end of the duct. Extensive testing with this setup and my case fans revealed that system heat was being transferred through the system/motherboard to the CPU. The CPU needs a fan, but so many other components are generating so much more heat that you're better off expelling their heat than the CPU's.

read that review carefully....
cpu temp went down a bit ~ but case and HD temps went way up! :Q wth?

i dont know about you guys, but the closer i get to a fan the cooler it feels
