Thermaltake ducting mod - effective?

[Tawcan]

I'm looking at the possibilities to decrease my system noise level as well as increasing cooling performance while spending as little money as possible. Right now I have AX7 and H1A.

There seems to be 2 options:

1.) Use a 80 to 120mm/92mm adaptor and use a 120/92mm fan.

2.) Use the Thermaltake ducting mod

I'm just wondering how effective the ducting mod is.

Which option would you go?

 

[SunRedRX7]

Well when I had my V11 I got about a 1-2C lower temp, and the temp controlled fan spun about 500rpm less with the duct mod.

I didn't really notice a decrease in noise.

 

[Vrykyl]

i find the duct is the cheapest and most cost effective solution

 

[Captain Hilts]

Has anyone else tried one of these out? I'm considering trying it out myself, some reviews seem to say that it works really well while others say that it doesn't do too much at all.

Would it be possible to hook this up to an ALX-800 and then put a Smart Fan on it?

 

[Blink Me]

you can hook it up to anthing that has holes for an 80mm fan. i wouldnt mind one to use on my PAL 8045 with my smart fan II

Ide ask this guy. Although this is not his current setup, he seems to love these things. His name on here is Clocker2.

BTW, i hosted this clocker, just so you know im not using your bandwith

 

[MattCoz]

Just that the ALX-800 has that weird clamping mechanism, the smart fan can't be put on it directly. Looks like it would work though.

Would it be possible to use the duct between the cpu heatsink fan and a window fan and still have enought flexiblitly to open the case side which the window fan is on? The distance between the 2 is about 5-6 inches.

 

[Hookem]

I bought one and it did nothing...Did not quieten the fan or lower temperatures...

Good idea?

I am thinking of using combining the ThermalTake Ducting Mod with a 120mm fan and some adaptors. Does this sound like a good idea? I'd rather not waste £20-30 on the bits if it's not going to make a difference.

Currently I have a Glacialtech Igloo 2500 cooler (2800RPM, 22.7CFM, 26dBA) with 70mm fan for my XP2600+ Barton @ 11x200. It looks like I'll have to change my configuration to the following:

120mm fan --> 120-80 adaptor --> ducting mod --> 80-70 adaptor

Thing is, I don't know whether it's possible to get an 80-70 adaptor. This seems like a very long daisy chain too!

[Edit] Knew I'd forget to say: idle temp ~40, load~48

in a word, no....

a) the fan won't like driving through a 120>80 adaptor - thats a 56% reduction in area... a second adaptor'd make it worse...
if you're after performance, best to try a tmd fan on the sink... (but it'd be noisy)

 

[St_Z]

I'll ditch that plan then. It seemed a bit far-fetched.

By the way, what's a tmd fan? Is it one of those "jet" ones?

One more thing: why do they make these adaptors if they're a bad idea to use? I'd always thought an adaptor would just have good effects like increase in airflow and pressure.

"YS Tech TMD (Tip Magnetic Driven) fans are driven from the exterior of the fan casing rather than the centre which eliminates most of the centre 'dead spot' normally associated with conventional fans, making them ideal for cooling CPUs especially."

their size makes them suitable for your 70mm heatsink i think....

Thanks for the advice. I'm not sure about the noise level, but the airflow is very good so I can probably put up with the noise.

With my current fan specs (see post above) my idle temp is ~40 and load is ~48. Do you think I should go for the 35CFM/25dBA fan or the 62CFM/39dBA one? Will I notice the noise difference much? I'm not very good at understanding the dBA units coz it's all logarithmic and I have logarithms with a fiery passion!

 

[FuzzyBallz]

Interesting. Now it looks like Dell hood mod. Too bad they only have a 80mm version. It'd totally kick *** if they have a 120mm version. I could then use it for the exhaust in my Antec P160.

You can always get the highspeed one and combine it with a fan-speed controller (like this Zalman one, http://www.ncix.com/products/index.php?sku=8840) since they're pretty cheap.

I wouldn't say that the high speed one is really noisy though, it just isn't suitable if you're going for a silent PC. It's nothing compared to one of those Delta screemers or the TT Smartfan at high speed. The lower speed TMD fan (or the higher speed one with the fan controller set to low) will be really quiet and you probably wouldn't notice it unless everything else in your case is really quiet as well.
