I hear some people on these forums get different fans for there exos, what would be the best fans for this, i dont want extrememly loud but i could live with some noise. also would i have to take the radiator off to get to the fans, i opend it before and it it doesnt look hard to take off, and how do the fans hook up to the power, is there any saudering required or do they just plug in. the reason also why i want to do this is because one of my fans makes a little ticking noise, its not noticable until u put your ear rite next to it though, so its not a big deal. but i hear these fans arent the best and by upgrading u can get alot better flow.
 
im looking to buy the exos but i was wondering how people are doing with it? How are people's temps with the exos?

i found the aluminum version for 220 and the black steel for 199. I dont REALLY want to buy online unless i can get a really good deal on one.
 
maybe look for a fan with the best static pressure to noise ratio, and fit a rheostat somewhere to control it's speed.
 
Well I ain´t got an Exos but the inbuild Koolance version which was the latest before it. It uses the same/tank tubes and everything so I think it performs exactly the same.

Anyway the fans I got pull a lot of air and pull a lot of noise too. I don´t really want to exchange these for some even higher performance and noisier fans as it´s.

I did however get a Sunbeam Rheobus fan controller and that is the best thing I could do in my hole life. Now I have a silent computer when watching dvd:s or doing other stuff when not pushing my computer to the limits plus I get great cooling when gaming and noise isn´t such of a big deal.

To me it feels kind of useless to change fans on this setup. It´s really good enough as it´s. My CPU temps never go above 45 degrees at full load and that is at 2 V.

And I am watercooling my northbridge too and it hasn´t affected the temps any from what I can tell. It just let me boost my FSB much more.

So keep it as it´s. Koolance got three modes of operations depending on temperature so you may want to keep the warranty and it may still be silent enough for you.
 
The fans just plug into 3 pin connectors, but theres no RPM monitoring!
You might try the medium speed Panaflo, it's got a pretty good cfm to db ratio !
I'm running spire aluminum case fans on mine and they work pretty well! they were thermal controlled but I removed the thermisters and shorted the wires for full speed operation!
They really put out some air and are quieter that the OEM ones ! :)
My system's not quiet anyway, not fan noise but air noise from the 150 cfm moving through the grills of the case ! I can pop the front off and it gets a lot quieter ! :)
Guess I'm gonna have to break down and make new grills for the front ! :)
 
The Koolance Exos AL (thats the aluminum version) can be found at Newegg for $210. Its a pretty good deal, and Newegg always has fast shipping.

Luck
 
The oem fans are rated at 27cfm.
That standard panaflo hi speed should ya just fine ! :)
 
those fans u linked are to big to fit in there. Another question also, if u put the planafo's in there will the mode selection still work or will they always run the highest speed no matter what mode your on.

No $hit, I wasn't serious about that. Basically, my question was opposite yours; I want fans that will provide the best cooling rather than ones that are quieter since I can deal with the noise.
 
It wouldn't do any good to turn the fans around to blow down because the unit is designed for the fans to pull the air and the efficiency would be dodo the other way !
I think anything much over 36-39cfm would be a waste and wouldn't improve the cooling any more !
All the modes should work with the Panaflo HIA fan, it's got a high enough working voltage spread!
 
im going to order the panaflos on friday:D from that one site. whats the easiest way to install these fans?
 
So far the differences I've noticed are that the hole where you would fill the reservoir has been moved from the bottom of the unit to the top, 2nd, on the AL version, the socket on the back of the unit where you would plug the power into now looks like a serial port and 3rd and most obvious, is that it is made out of Aluminum. Don't know if the aluminum has any affect on the cooling though. Hope this helps

It does on most other parts, but I don't know how the EXOS works and havn't seen any numbers yet.

The main reason the did a AL part is the weight really. If you where aircooling it would help but with watercooling the effect is greatly diminished.
 
Well, if it helps, the temps I get on my 2400 (non oc) at idle is about 85F (+/- a few depending on room temp.) and at load I've never seen higher than 98F. When I leave Folding@Home on while I'm at school, I see temps around 95F (stupid monitor keeps my room pretty warm though). I'm using the regular Exos, not the AL.
 
when i put my fans in can i just use quick disconnect and leave the water in there why i change out the fans?
 
Yeah, you can use quick disconnect, then unscrew the unit, remove the screws holding the radiator in place, then change out the fans.
 
wich fan panaflo fan should i get, the one with rpm sensing or the one with out rpm sensing, or does it even matter?
