best performing 120 rad? any got some advice.. - Page 2

post #11 of 18
First, the Alphacool UT60 is the best performing rad series followed by the XSPC RX series. You can see the best rads shootout here:http://martinsliquidlab.org/2012/04/14/360-radiator-shootout-summary/ Second, the X-FLow is a single pass design which has worse performance than the much more common dual pass designs of other 120mm rads. The only reason to use an x-flow is if you need the input on one side and output on the other due to some space constraints in your case. If you can configure your case to allow the rad input and output to be on the same side, use a standard radiator.

You did leave off a few details such as how fast of fans are you looking to run, how much better performance are you looking for, what is your current water delta? These answer will determine if you should get a low FPI or high FPI rad.

Not all the xflow designs are single pass. Take mine for example its a dual pass.

And the 360 rad i have outperformed a 360 rx head to head with the same 2000 rpm fans.

The xflow is if you dont like tubing clutter as i don't.

Also your article is 1 year old and the stealth series is new and outperforms the gtx series as they stated themselves.

On Martin's site, it's pretty clear the Alphacool Full Copper series rads are the best performing rads. But performance is only half the story: the UT60 is one of the most restruction free rads. And performance wise, beats everyone else at all fan speeds, except below 1000 rpm, where it's still a top performer.

Full copper, copper fins, copper tubes, and copper chambers. Everything the water touches is copper.

Best rads are the Alphacool Full Copper series rads PERIOD

Want the best rad at all speed range?
Get the UT60.
They cool so well that ten of them will end global warming.

Which X flow rad is dual pass? and how would that work?

In must rads the flow works in a U shape ... the water enters one port, travels through the tubes on one side of the rad to the end tank then back through the tubes of other half of the rad to the outlet. That gives you the two passes, even though its only half the width of the rad at a time.
A X-flow rad just has the flow going from the inlet, through all the tubes of the rad, to the outlet on the opposite end. Its single pass but using the entire width of the rad.

I don't know for sure but I would think that given the same surface area that the cross flow and U flow rads would produce quite similar results, just with less restriction in the X- flow because it uses all its tubes in one direction, rather than forcing the flow through one side then the other.

Ok, so the Alphacool are the best.. as i have max clearance of 40mm before i hit theMob, what would be the best choice of rad..?

does the Alphacool stand up to be the best cooler in the copper range? for instance

Alphacool 35265 NexXxoS ST30 Radiator 240 ( http://www.scan.co.uk/products/alphacool-nexxxos-st30-full-copper-240mm )

also for the 120 rad would this be a good choice Alphacool NexXxoS Monsta 120 ( http://www.scan.co.uk/products/120mm-alphacool-nexxxos-monsta-radiator )

Thanks

Uhh.. you might want to read the specs on the rad you own. Per: http://www.hwlabs.com/index.php?option=com_content&view=article&id=33&Itemid=30 "Single-pass low resistance cross flow tank configuration."

single pass perform worse than dual pass because the water flows through the rad faster than it can be cooled by the fans. Basically it flows too well and minimizes the cooling exposure. Martin and skinnee did a write up on this awhile back. X-Flow pro is less restriction and tube routing, con is worse cooling performance than equivalent size and FPI dual pass rad.

Oh and also a 120 in the back is a very snug fit the one i had didn't fit with the equipment i have it pretty much sits on top of the gfx card.
Running the tubing was near impossible. i gave up.

ok went for the Black Ice GT Stealth 120.. will be arriving tomorrow.. will hopefully set it up with a push pull with Corsair 120 sp.

Thanks for the advice.. will post the temp benefit from adding to the loop.

cheers
