As title, is this rad a worthy contender or are there better rads out there?

Also, would I be able to squeeze 1/2 inch Tygon into a gap about a centimetre wide (obviously a little smaller than 1/2 inch) without too much restriction on flow?
 
:) Poor quality chinese made rad on the cheap

PA120.2 would perform better

If you MUST have a .3 , Black Ice Stealth or Pro are decent for the money... the NexXos Extreme is a cheap copy of the Black ice Extreme...

The thermochills really are much superior in both build quality and finsh, as well as performance

1/2" ID = 3/4" OD
3/4" = 18.25mm roughly

wouldnt want to put that in a 1cm gap myself
 
ADDENDUM - JULY 2006 - Further independant comparative results vs other rads - Testing Performed by Radical_53 on behalf of HardwareLuxx Magazine - Germany

120.3 radiator formats tested. Results scale down perfectly for all other formats (120.2, 120.1) from same radiator family (as originally proven in BillA's testing of the HE Series MANY years ago)

1 - Pressure Drop - flow set at 4lpm at pump, pressure measured after radiator. % loss shown - smaller the loss, better the head pressure... listed best to worst.

Least Pressure Drop...
ThermoChill PA120.3 - 6%
Watercool HTFX3-x - 14%
HWLabs BlackIce GT360 - 17%
HWLabs BlackIce GT360 XFlow - 17%
HWLabs BlackIce Xtreme - 17%
HWLabs BlackIce Xtreme XFlow - 17%
Watercool HTSF - 17%
Cooltek MCR320 - 18%
NexXxos Xtreme - 23%
NexXxos Pro - 27%
...highest Pressure Drop

As you can see, you could theoretically run TWO Thermochill rads, and still have better head pressure than if you were using a SINGLE rad of any other brand.

2 - Performance order (best to worst) based on final coolant temp, cooled with YateLoon 120mm fan - lower the "k" figure (difference between coolant temp and air temp), cooler the coolant, therefore better the performance...

At 600rpm:
Thermochill PA120.3 - 7k
Watercool HTSF - 8k
Watercool HTSF3-x - 8.4k
Cooltek Maxistream / Swiftech MCR - 8.4k
Black Ice GT - 9.2k
Black Ice Extreme - 11k
Alphacool NexXxos Pro - 11.2k
Black Ice GT X-Flow - 12.1k
Black Ice Extreme X-Flow - 12.3k
Alphacool NexXxos Extreme - 14k


At 900rpm:
ThermoChill - 6.2k
Cooltek - 6.9k
BIGT - 7.2k
WC HTSF - 7.3k
BIGT-XFlow - 7.3k
WC HTSF3-x - 7.4k
NexXxos Pro - 7.5k
BIX - 8.5k
NexXxos Extreme - 8.5k
BIX-XFlow - 9.5k


At 1200rpm:
ThermoChill - 4.2k
Cooltek - 5.6k
BIGT - 5.7k
BIGT-XFlow - 5.9k
BIX - 5.9k
NexXxos Pro - 6.1k
NexXxos Extreme - 6.1k
HTF3-x - 6.3k
HTSF - 6.3k
BIX-XFlow - 6.6k

As you can see, Nexxxos Extreme is one of the worst performers of the 10 rads tested.
 
Thanks for those replies. The reason for considering that rad was it fits perfectly in my case. I'll rule it out. I'd love the PA120.3 but unfortunately it's just slightly too tall for the space I have. But it looks like the Swiftech MCR320 120.3 will fit even better than the NexXxos. While its pressure drop is on the higher end of the table, the results look quite good. Would this be a decent choice?

It must be 415mm or less in height :)
 
As long as you're using fans that move more air than a YateLoon does at 900rpm, then it should perform fine...
 
I have the Extreme lll triple rad and it does very well for me. I had 3x 120mm Akasa Ambers (1400rpm/44.8cfm allegedly) on it but have now changed them to 3x120mm Thermaltake Thunderblades (2000rpm/78cfm allegedly). There has been a degree or two drop on load so it paid off. The fans are mounted on a shroud that sits them 40mm above the rad and the shroud/rad join is airtight.
 
The nexxos extreme rad(dense) is for high flow fans, the pro rad is for low flow. I have a nexxos pro 120.3 which cools my conroe e6600 @ 3.7 (1.55v) to 22 idle 36 load(speedfan) which makes it pretty damn good imo and I find it hard to imagine that a thermochill or any other rad will be substantially better to justify triple+ the cost. For the money I don't think you can go far wrong.
 
why so set on the triple rad? You need to be cooling a lot of hardware to see any significant benefit over a double.

A few reasons for a triple:

1) I currently have an overclocked dual core Opteron and in the future this iwll be cooling not only the CPU but chipset, probably SLI and possibly the hdd's too (not sure about the hdd's though as there would probably be a lot of flow restriction).

2) The system will be aimed at silence rather than total performance. So a tripple rad will allow me to run slow fans (sounds like the Swiftech is ideal).

3) It will be fitted in an ATCS S4000 case. This is an unusual case which not only has rear and front fans but also an extended middle section with fans to direct air over the motherboard. The intention is to mount the rad entirely internal in this middle section. A triple rad would mean that, with some foam edging or possibly some plexi, I could completely isolate the front and rear sections of the case (not 100% air tight but not far off). This should mean that, with a middle section comprised entirely of three fans stacked on top of each other (and a rad of course), clean cool air would be drawn through the front case grill (also top to bottom) over the drives and through the rads. A double could do this of course but a triple would do it with less fan noise.



So I've just gone for the Swiftech. It seems the best fit in the case and most suited to low airflow fans. Thanks for everyones input though.

I aint saying that the thermochill is not as good but do you really think that it would make so much of a difference to justify almost triple the cost? :p

Does the 25,962 rpm fan not make it a bit noisy thought? ;)

Lol, didn't notice that...wondered what that irratating whining noise was - thought it was just the wife. :p

I use 3x thermaltake thunderblade fans (78cfm if you believe what TT say) more for the looks (blue led) rather than performance as I have them running on lowest speed through a fan controller anyway. They can get noisy on full but are near silent on slowest setting. There is little difference at load between high and low fan settings (3 c max) so I only really have the fans on full when benching. They are all hooked up to a coolermaster Muskateer which unfortunately dosn't give rpm, just voltage (7v-12v).

And you trust the CPU Temp readers on your mobo??

/me recalls the Abit NF7-S, which read 38 deg C for CPU Temp with bios rev16, but with bios rev11 read CPU Temp as 19 deg C, and with rev21 read 32 deg C, and with rev10 read over 40 deg C
 
lol...no I dont trust on board diodes marci (I believe we're also discussing this @ XS ;)). I just get a guestimate from the average taken from PCprobe, speedfan, TAT etc
 
can you use coretemp?

the last time I saw a cpu idling at under 25 it unsettled me because I just assumed it was incorrect.

I've always seen 30ish as about the lower limit unless its bloody cold

I guess it depends on what you class as 'incorrect'. Core temp/ intels TAT show roughly +10c idle / +15c load (32/47) depending on vcore but not many people seem to 'go by' TAT/core temp so for comparison I used Speedfan which uses the socket diode as do most other programs.

As stated I go for an 'inbetween' as a guide as no monitoring software is truly precise imo
