Meh, What was the overclocking difference. I've ran tons of setups and two degrees has never made difference in stable overclocking. Also I run two GTX's a 240 and a 360....so i'm not about to change radiators lol

Hooray! some w/c reviews! Can we have some reviews of Aquacomputer gear?

damm it why do you constantly tempt me to go watercooling with the new rig i intend to buy

Damn you could have warned us to turn off/on/up/down our speakers before we clicked the link to the xchangers "INFORMATION" scared me half to death.

Yeah, but not quite how you're taking it - I would be putting the two GPUs in one loop and the CPU in a separate, smaller loop I guess? I hope that makes sense. :) That's asking for an awful lot of heat in one space and for the cost of the equipment, I'd think there would be a little money to plumb into two loops.

Sorry about that... yeah, I'm really not too sure what's with all of the music.

What are the fan specs and were they mounted in a "push" or "pull'" configuration?

An incorrectly spelt portmanteau of game journalist? Why does bit-tech find it so hard to use spell check, maybe they don't want to be bothered by all their made up words being underlined in red.

Are there any radiators which work well with large case fans?

Now that I have actually read the whole thing I can make a constructive comment.

Good review of all 6 rads, makes me want to WC, I just keep getting tempted, and dispite what people keep telling me I know 240mm rad would be perfect for my system.

"Roughly translated, this means that if a system can dissipate 75W and 95W of heat respectively and you're only putting 25W of heat into it, both will cool similarly assuming equal flow. However, when you start dumping 65-70W of heat into the system, you'll find a sizeable difference in temperatures between the two."

Thats is the best way I have seen the performance of radiators explained. Makes me realise that for my system there is no point getting the best rad money can buy.

My only gripe is the lack of testing with other fans/speeds, I know you touched on it but I would have liked to have seen a @5volt and @7volt chart, as most people wont be running fans @12volts. I would say most run at @7 and at that speed the differences between the rads performance may change drastically.

Also I hope that you add the charts from this review to the next one so we can have a side by side comparason of all radiators to date as the review process goes on.

But other than that, great work.

hey now, I spell check very carefully, thank you very much. Very few of my articles contain flagrant typos. ;) At least allow me one once in a blue moon?

As for "large case fans" - define? If you mean 160mm, there's really only one on the market right now - the ThermoChill PA 160. 120mm is really the fan standard by most accounts.

Bit harsh, and it is probably because it is written in notepad as its fast and easy and all the formatting is done the website end so there is no need for word processing.

Big case fans? These rads take 120mm fans, they are big case fans

:? PA160 uses a single 120mm fan. Is that what you meant? ;)


I'd really like to see a head-to-head with PAs versus the Fesers. Those two are really the same class in regards to fin-count and style of rad; i.e. designed for silent operation with lower-CFM fans.

Edit:
Forgot to say thanks for the review, guys!

What about the GTX 480? It is the only 4 x 120 I know of but it does has that coolness of having a huge rad with out going up to auto rads. I currently running one in a stacker with a push/pull fan setup
RinSewand 23rd May 2008, 14:42 Quote
Yeah i'm with E.E.L. The thermochills are generally thought of as the best performing radiators in most reviews i've seen, and the fesser is a similar design. perhaps could you include a 7v test for those? as i know the PA series is designed for use with quiet fans, or normal fans at 7volts, and is where it excels, and is the more likely scenario in day to day use for most people.

hehe ;) Yep, thank you for translating. I moved thoughts and just kept on rollin.

The Thermochill one will be coming soon, we've had some problems due to supply chain issues. :) I will try to add some 7v tests in there as well when I do that one! :D

Looks like Feser's releasing a 480 rad as well.

No offence intended* and I did not direct it towards you specifically, but Bit-tech in general. No offence to Bit-tech but I have seen a few typos which would be picked up by a simple press of F7. I don't want that to be misinterpreted so I would like to clarify that I meant (and typed) "Why does bit-tech find it so hard to use spell check" (the function/feature) not "Why does bit-tech find it so hard to spell correctly". Okay?

Alright you're off the hook *takes Da Dego off the hook* ... Does Da Dego like being on the hook? You appear to be hooking yourself with your finger.

The XClio Wind Tunnel case to be specific. Obviously I'm not expecting 220mm(x 220mm) radiators (the fans are really 22cm rather than the claimed 25cm) but as the fans move so much air I could put a radiator (or several) inside the case and tape off some vents to force the air to go though the radiator(s). Trying to use the case fans with the GeminII did not work so well (it might have been a mounting issue due to CoolerMaster's useless instructions but after I tried to remount... the motherboard wouldn't boot).

*Maybe you took offence as you had already corrected yourself, I'm sorry for not noticing that.

Hello guys, great article. Anyhow I have a small question.

I have the Lian Li PC-P80 case and have now got water cooling, where is the best place to put the radiator in such a case?

Isn't it obvious? :)

Depending on how much cooling power you require, and if you wanted it internally, you can mount a single 120mm rad on the exhaust, or single, dual or triple 120mm rad up in front. Or get even more creative.

I would have liked to have seen if a fan shroud made any difference at all to temps, in addition to this, if pull or push is better and what about fans on both sides of the radiator.


Please! These things I must know!

It's been documented before many times on many forums. Fan shrouds may make a difference of a degree or so; nothing drastic. Push or pull is quite debatable (and is, daily!); in my personal experience on all the WCed rigs I've done for others or myself, pull is better for more silence and efficiency. Having fans on both sides of the rad only maintains pressure; again, not a drastic difference in temps if at all for the added noise.

The truth is, try it out for yourself, and whatever works for you, works for you!

Thanks for the review! Wish I had the money to tinker with water cooling... maybe some day.

I have not fully read a review for a while. But this review really hocked me and kept me reading word for till the end. Great review I really enjoyed it.
