great idea, concept, and appearance but just not worth it for the performance gained over its cost, oh well.

It does seem a little odd putting the pump on the cpu block, especially as they tend to dump heat into the loop? I also currently run a single loop for GPU and CPU (although obviously custom) and would not recommend it, modern graphics processors dump so much heat it scares me sometimes to look at the CPU temps ;)

^^^ well the whole pump/block combo type argument as been around for a while and honestly a pump makes next to no heat so really there isnt much of a change and this looks like its using the Siberian block/pump combo which is the only competition that I know of to the swiftech version but as far as I know isnt sold in the states. Either way it offers no better then low level entry water cooling comparable to that of high end air cooling.

There is no way the single "slim" 120mm radiator could cool a high mainstream gamers CPU (such as a Q6600 or Q6700) AND a HD 4870 X2 comfortably. As your tests show the CPU actually ran hotter than stock. Just a gimmick.

^^^ at stock no problem, again that setup has similar results as highend air cooling, OCed well if we are talking q6600 up to 3-3.2 ghz would be alright but anything higher well of course not.

they should have just released the card with the waterblock on. i think they have narrowed their market by producing a entire loop

Would also be cheaper for the consumer to purchase (if they have a pre-existing loop).

Would be interested in three things... temps with a Q6600 rather than the heatmonster Prescott, temps without a CPU in the loop and what sort of difference adding a second fan on the radiator in a push/pull arrangement will have. I realise that you probably aren't going to be testing those, though, as you've likely got better things to be doing. ;)

Even so, this is a nice idea that fails because a single 120mm radiator really can't take two hot GPUs and a CPU all at the same time. A dual would have coped better, but even then wouldn't have been perfect... and case compatibility goes out the window with a dual radiator.

If it's going to be cutting close to £600, that really doesn't do well enough to be justifiable. A 4870X2 and a decent custom watercooling setup will cost the same, and give far superior temperatures. Of course, that introduces the whole complexity issue again... :)

Great review (I love how in depth Bit-tech go for these reviews and also the inclusion of min framerates are a god send compared to other reviews)I can't help but think thought tthat the choice of wording 'heavily overclocked' seems wrong for this card.

In reality its a bump of 50mhz on the core and 100mhz on the memory (quad pumped for GDDR5) is simply just an overclock.

Maybe its because I am used to seeing card like the my old 8800GS (XFX alpha dog edition) clock from 550 - 750 on the core, 1500 - 1950 on the shaders and 1400 - 2100 on the memory. Not thats a heavy overclock!

Crompers:Ditto,was thinking the same.Sort of along the lines that BFG took,i think,with some Nvidia cards.

So....in the new year its a choice between a £600 Gfx card or food and water...

I'll choose the latter, but want the former...

Looks like they should have done just the GPU and left the CPU cooling to whatever the consumer wanted/had to use.
I've always wondered about having separate, dedicated loops for CPU cooling and GPU cooling .. from the figures, it looks as if a single 120mm fan/rad would cool the 4870 x2 just fine, and without the GPU dumping all that heat into the CPU loop, I wonder if another 120mm/rad would cool it too?

The US price is supposed to be in dollars, ahem.

Will the 4870 X2s ever drop below $350, I would really like to get an X2 over the regular one, but the price is so much higher.

Eh no thanks!

So lets say you have the cash for this, then in a few months want to buy another card for crossfire? What are you going to do with the extra cpu block and pump?

I apologize for not reading the whole article, I just skimmed through it before heading off to class, but is it possible that you didn't get a good mount on the CPU waterblock? The only other review I've read about this card said the CPU waterblock did a very good job.

Double checked and fitted twice - it's not that the waterblock does a bad job, it's just that the loop struggles to deal with all the heat being dumped into the loop by the 4870 X2, the point where the CPU is actually being warmed by the loop rather than cooled!

US Price (as reviewed): £700 (ex. Tax) - MSRP

Shame they chose 1/4" tubing.. 1/2" or 3/8" might have made some slight differences, but it's pretty obvious the radiator was just incapable of dumping off the heat.

I wonder if it's a dual-pass radiator, it's look a bit too thin to be dual-pass.

The concept is good though.


Wouldn't the fluid eventually need to be topped up though?

Interesting how it didn't have a reservoir either, so it would mean the system has the exact amount of fluid. I wonder if it makes any thermal difference to have reservoirs for liquid to sit for a while and dissipate heat before being pushed back through the loop..

did you guys try to squeeze any more performance out of it? or didn't want to risk it?
Drexial 19th December 2008, 16:29 Quote
I wonder how it would do if you mounted the CPU block to the case.... It clearly isnt doing any good for the CPU which would be better air cooled with this loop, and with the heat dissipating into the metal of the case. Might bring down the temps on the GPU even more. The temps were pretty low on the GPU, but yeah just not a good system to include the CPU in.

Sapphire list the the life expactancy of the card at 50,000 hrs - over five years, so it doesn;t look like there'll ever be a need to refill.

With the CPU temps so high we really didn't want to risk it. While we're sure you could push the card a little higher, the resulting increased thermal output would have put our CPU in danger, and as it;s our only one, we weren't going to risk it.

So... taking a $500 card, overclocking it, and slapping a WC loop and rad on it suddenly justifies $700? Could I get it for $625 without the ridiculous e-peen enhancements like the metal case?

When will these companies LEARN!

They just CANNOT produce anything even close to what you can do if you buy the individual parts yourself for a water cooled loop.

(US dollars so sorry)

Pump: $50
Tubing: $20
CPU block: $75
Rez: $30
GPU block: $75
Radiator(+fan & fan speed controller): $100

Look at that! a fully functional water cooled loop for around ~$350

~400 - 500 if you include shipping! (and may need a second gpu block!)

So now you spend 500 bucks US, and you have a fully usable loop that not only works AMAZING (compared to the mass produced crap) but as long as you buy it at the beginning of a new format cycle (CPU / GPU mounting style) you can still upgrade your system without having to worry about upgrading your loop.

Hell, for a 100-250 (US) you can upgrade the loops key parts to work with your new CPU / GPU mounting setups


These companies will never learn, offer the water cooling community a setup with quick disconnects, the ability to buy an upgrade kit every few years, and you have a easily marketable product to that niche.

'£575 is a whole pc in the land of real people.

No sane person will ever pay £575 for a graphics card

sorry amd/ati but no way ever ever
