    Need a High Performance heatsink fan

    I am using a Arkua 7528 heatsink/fan on my XP2000. It cools pretty good but I want to do a little overclocking and I want a more powerful fan. The fan on this heatsink is a 70x70x15mm with a 36.26 cfm rating. I would like another 70mm fan that has more cfm's then this one. I have looked around at allot of websites and I can only find 70's that run less cfm's. Does anyone know of a fan that fits my requirements?

    don't know if there are any 70mm fans that will push more then that.

    That's about the best I've seen.
    Those Arkua's are pretty neat heatsinks though... Hate to have to swap it out for something else.

    Well I think if I can't find a 70 that pushes more i'll try and find an adapter from 70 to 80, if they make them.

    These Arkua's are great, I really like mine. That's why I want to mod it instead of changing it.

    I had this on my T/bird 1000 and one day I was doing something, testing a processor I think, and I forgot to plug in the fan lead and turned it back on and left it for about an hour, came back in and smelled it and knew what I forgot to do. I couldn't plug it back in because it was so hot so I used some needle nose pliers and plugged the fan back in and watched the temps go from 97 celsius back down to 38 celsius.

    With one of these adjustable fans....

    would make for ALOT more airflow... the aerodynamics of having the adapter funnel the air down to a smaller longer passage, in of itself, will improve the cooling and reduce if not eliminate any "dead" spots you had before...

    Thanks for the links JPMiller, I really like this fan http://www.svcompucycle.com./thersmarcasf.html.

    As far as dead air is concerned, that is the main reason I like this style of heatsink, that dead air in the center of the fan is not an issue because the heatsink fins are directly in line with the fan blades.

    Do you have a window?
    What are you using for thermal compound?
    have you lapped the bottom of your heatsink?

    No I don't have a window, eventually I'll put one in. I'm just using regular heatsink paste, the Arkua is machined so good I haven't had to lap it. When I start doing this overclocking I plan on lapping it though. My friend has a tube of AS3 that I can use.
    I like that "TRIBAL SUN" grill but it says it's out of stock.

    get an 80mm to 70mm adaptor and get an 80mm thermaltake smart fan II(if u prefer performance to fancy)

    http://www.thermaltake.com/products/dcfan/a1357.htm

    LOL i just posted this and after that I just realized that JPMiller already posted the same fan

    anyway I have this smart fan 2 and it sure is windy, but noisy as well

    Thanks Ranma, I have a nexus fan controller so I can run it at half speed until I need it.

    Your HSF looks about identical to the Thermal Integration V77L. The fin design (open bottom) should make the fan adapter idea work very well. Most heatsinks have a closed bottom design. That and the restriction of the adapter creates enough back pressure that temps often go up with an adapter solution. The v77L works very well on its own. I'm about to adapt mine to an 80mm fan. I've notied that the adapter doesn't fit down into the plastic deal on top of the HS. I'm going to use some rope caulk to fill the gaps and provide a smooth air tunnel. I'm going to try the lowest powered 80mm I have on hand first - I want some quiet with my cooling.
    . The standard 70mm fan on mine is a feisty little bugger - 0.40 Amp!

    no, you don't need another fan speed controller, it thermaltake smart fan II comes with its own, and with a speed sensor, too..
    (thats why its called smart fan )


    silly me, I just realized the nexus is placed at the drive bay

    Hey zepper, the design of these heatsinks I think is far better then the basic design of heatsinks in respect to using the fan to it's best ability. By that I mean most fans have a "dead spot" in the center of it and this vertical fin design works great to take advantage of that. I have a my fan controller set at half speed and my cpu temp is 32.0 celsius.
