Fanadaptor on the cheap... :D

[Intraveinous]

My girlfriend has become quite the herbalist, growing all kinds of stuff... The other day, she was picking out some new herbs at the greenhouse when I saw the pots they were coming in... They looked to be a bit larger than 8cm at the top and a bit larger than 6cm at the bottom. I had her grab me an extra one... Sure enough, I was right... I've been wanting to try a fan adaptor on my Zalman CNPS-5000+, but I just haven't gotten around to ordering one, and I had been thinking about just making one, guess it's time to get down to it.. Basically, I punched holes in the bottom of the pot for the screw holes of the heatsink, then cut out around those holes to have an open bottom for airflow with a pair of diagonal cutters. I screwed this assembly to my Zalman heatsink, and just pushed my Delta 80mm 68CFM fan that originally came with my MC462 down into the top... I have it set up to blow down into the heatsink currently.
DISCLAIMER: All temps are from the in socket thermistor, so discount it if you like...
Previous temps on a Duron 750 @ 750 were approx 36C full load with a room temp of about 20C. This was with the stock Zalman Fan.
New temps with the fan adaptor:
Full Load shown by Prime95 Stress for a lil more than an hour:

"Sure," you say, "it can cool a Duron 750, big fricken deal..." So I stuck an Athlon 1.33 (fastest I have sitting around) in there and tested that too...

Previously, with the stock fan on the 1333... I would get lockups about 10 minutes into Prime95. It finished about an hour of Prime95 a lil while ago and I've been surfing since then, no lockups, no problems... Sitting around 29C Idle (surfing only)...
So all in all, for $0.00 and ten minutes worth of work... I'll take this fan adaptor and like it... :D
I'll try to borrow a digicam tomorrow and get some pics of it... It's ugly, giant and generally dumb looking, but I don't really care, I'm running at 1333 instead of 900 or 750, which I previously couldn't do...

a bigger pot can be used to make a fan intake look nice aswell

Cool Experiment. Find the Comair Rotron fan that pushes 550cfm and see what your temperatures are :)

You can also try this (http://forums.overclockers.ws/vb/showthread.php?threadid=52995)(just scroll down to my pic). You also get a nice drink from it:beer:

Heheh... :D Yeah yeah... I really don't think they'd drop any... I have to run the system with the side panel off anyway because of the hieght of the adaptor and I have about 200 CFM of ventilation in the way of case fans, blowholes, etc... That 550CFM Comair is a 10 inch diameter fan, so it'd pretty much replace the side panel.. With something that beastly, I don't think I'd even need a fan on the heatsink... I don't think that the noise would be bearable either... Oh wellz... The things we go thru... One big plus is when I turn the fan all the way down with my rheostat, it's quieter than the stock Zalman fan and cools better by 1 degree... I do have the problem of a hot ass rheostat, but I just hang that in the path of my front intake and it's taken care of...
I'll try to get a digicam sooner than later...
Thanks for the other ideas...
Peace

any pics yet? sounds interesting.

[RangerJoe]

where can i get those comair fans?

Sonny - You can get a better drink with my Bud Fandapter. :beer:

[Sonny]

Colin - LOL No way!!!!!!!!! Your suppose to have some JD with it:D On a serious note people should really start to look at their funnel/duct/adaptor designs/creations with regards to the airflow thru the actual unit. How does no back pressure & increased efficiency sound to you guys? That's what this stack can do.

[Colin]

Sonny- I think it's called a plenum. A velocity stack would be on the intake side of the fan. In any event, it should out perform my Bud Fandapter (now retired BTW.) Good idea. :D

[Intraveinous]

OK... FINALLY borrowed a digicam and took some pics... They're pretty fuzzy, but hopefully you'll get the general idea... I need to get some new lights in my room before I try to take pictures again... :-D

Kinda hard to see.

2 case fans funneled into a fop

Intraveinous - I like your design. Very simple and very effective. I did kinda the same thing but instead I used the very thin plexiglass w/ rubber cement and magically it becomes an air duct. I might do your way instead since the duct is more concentrated towards an area and not like my duck that blows out in an spread motion. But I think for your potduct you can try to get some kinda of vaccum tube and hook it up to the end of the duct and the other end blow right in front of the HSF. Which means the HSFS is getting direct air flow.

[Brant]

If you look closely at my design I origionally had just a standard fan adaptor -look at the fan mounting holes-. I just added the rest to that. But the way to glue the plexi together is with acrylic cement it is great and strong. It uses capilary action to suck the cement into the joint. So you set the whole thing up then put the cement on. It costs like 5$.

[Brant]

oh yeah the 1/8 " plexiglass costed 50 cents (scrap)

[adamtekh]

would that be a 7237 case ?

[Intraveinous]

But of course... :D I've had the thing since I had a K6-233, it still holds some nostalgic value to me... :D
It's been thru just about everything, stuff falling off shelves and putting a big dent in the top, my very first blowhole with a dremel (it wasn't pretty)... hehe... I think I'll have it forever...
