60>80 adaptor + 80mm fan on HS - any benifit?

edited June 2003 in Hardware
I have a coolermaster Heatpipe on my CPU (XP chip) & i'm thinking of fitting a silent 80mm fan using a 60 > 80 adaptor to try & reduce my summer temps.

The factory default fan on the HS has a CFM of 14 & the 80mm fan that would replace it would be 27 CFM.

Would i notice a considerable temp drop with almost double the CFM, or would the 60 > 80 adaptor height comprimise the cooling efficiency too much; negating any additional cooling effect due to not being directly attached to the HS?

    You would see some benefit, especially if it's a stealth 80mm (quiet) and decent cfm (the stock thing sounds like junk, so just about anything, adapter or no adapter, will help).

    80>60mm converters can do more harm that good as most of them end up blowing back more air on themselves than they actually blow into the Heatsink, also for the same reason, they can end up being nosier. If you are sure you are going to do it just make sure its a very high quailty conver that you use.

    An 80mm can blow the same amount of air at a lower noise level. The 60mm fans tend to have much higher rpm levels and a high pitched whine that bugs me to get the same airflow. I have never used the adapters. I run all 80mm fans on my heatsinks and all are either temp speed controlled or manualy speed controlled as I use them to reduce noice not get better cooling.

    Thanks for all the replies.

    Tex, how do you attach the 80mm fan to a HS designed for a 60mm fan - as i would probably prefer that option?

    All his heatsinks are designed for 80mm fans.

    I run SK7's on both my dualies and my KR7. Five total. They come with a variety of little wire attachment thingys that fit differant width and size fans.

    I have three 80mm manual speed adjustment Enermax fans and two very very quiet temp controlled speed adjustable fans on one dualie.

    Sorry if I wasn't more help. I swear by these sk7's. Best combo of performance and price on the market right now IMHO.

    AX-7 is still a sweet deal too, just below the SK7 in performance:

    You've helped a lot (besides running these boards) - it may be that i should spend a few more pounds & get a completely different HS & fan combo. I went for the quick solution with the initial build but the Coolermaster HS/fan aren't proving to be as effective as i'd hoped.

    I'd never considered a HS big enough to accomodate an 80mm fan before, was always worried about the weight, but perhaps i should look again.

    The reviews of the SK7 & the AX-7, which stoopid pointed out, shows me that perhaps i need to just buy a whole new unit.

    Thanks for all your help guys.

    Best way is to cut a hole for a 120mm fan in side of the case blowing over heatsink. That will allow you to have low RPM fans that push a lot of air so its silent. Ive done this for a friend and it dropped his temps by 10*C.

    Almost everyone has the fans in the side pulling air out. You and I may be the only guys thinking that blowing cooler air straight on the cpu/HSF is better but my temps have always been better that way.

    The fan on the side of the case would probably be a cheaper & easier option to start with – it would save me removing my MB to get a new HS on.

    I haven't got a Dremmel (wierd electric cutting type tool) - can you recommend a manual type saw? I've got an assortment of hacksaws but the frames holding the blade aren’t really conducive to cutting out a 120mm diameter hole.

    Any manual methods/tools you’ve used that you guys can recommend?

    You can either drill a load of holes close together and cut it that way with pliars or something, youll have to file it down to get any kind of acceptable finish.

    The best way however has to be the holesaw. Grab a 120mm holesaw, theyre quite cheap, some cutting oil, and a WIRED drill, a drill press would be even better, and cut it out. With this method only a little filing will be required.

    Either way, mesure twice cut once, and use plenty of masking tape or youll need a new paint job.

    The hole saw sounds like the way to go - had no idea they went up to that size. (Thanks for the masking tape tip.)

    The other thing would be an air filter (as i will be blowing air onto the HS). Is there a specialist material i can use - or perhaps some generic piece of material electricians/techys use that i don't know the name of?

    Thanks again for all the help guys.

    Ive tried using foam before as a filter, but it restricts airflow because i cant get thin enough foam.

    Head on over to:

    http://www.kustompcs.co.uk/product.php?subcat=17

    Theyve got the generic ones and some fancy metal ones that look pretty cool too, bit more expensive though.

    The guys at Kustom are great. Bit pricey but you cant fault the service.

    Another tip for cutting blowholes is to use a T square to get the holes straight, and square to the edge of the panel, or the mod will look tacky.

    Excellent, thanks dydx - for the link & the additional tips.

    Really appreciate all the responses to this thread - think i'm sorted.

    I'll fit the side panal fan over the CPU area, using ur drill/saw method. Then replace my 2 existing case fans for silent, slower fans. And then finally replace this aging PSU for a silent PSU - which, i hopefully will be able to run on silent mode thanks to the added side fan.

    Perhaps then, i'll have a cool, semi silent system.

    Cut the fan hole covers off too, these produce a fair bit of noise, and block airflow.

    The acoustic padding stuff from Kustom cuts a fair bit of noise aswell.

    Thanks for all the advice dydx.

    I'l prolly attempt this mod within the next couple of months when i plan on getting a silent PSU.

    Additional: I got the SATA drive installed plus partitions with nps what-so-ever (to date) - thanks again for your help on that thread too.
