Quick question if what size radiator do I need to cool 2 x Radeon 4870s?
Full story below if your interested:
I am getting some samples of water cooling kits from China in around a week and am planning to test them and if they are any good resell them in the UK. I have a Phenom 550BE unlocked to 4 core and running at 3.5GHz and want to cool this and the motherboard on 1 loop and also want a separate loop for 2 x Radeon 4870s. If these systems are any good I think I need a 120.2 (I think thats what its called for one the size of 2 120mm fans) for the CPU & board but what size do I need for the 2 4870s? I will be getting a selection of radiators so I should have whatever I need. I am also getting a selection of air coolers to compare as well and will post the results for all to see in a week or 2.
Most rads have stats/specs for them, and you can generally look up how much power they can dissipate for a given air flow so that way if you pick the fans you want, you'll know your airflow and can decide on the rad.
a 220 is probably sufficient but a 320 would be prime
I'd say for the gfx cards, a sandwich.
2x 120mm fans >> a 120.2 Rad>>2x 120mm fans>>
Where >> denotes airflow, preferably exhaust out the rear or top of the case
You watercool Moto?
NO, please don't sandwich radiators. Tests have proven unless you have 6 fans in total for a 120x2 radiator, and high speed, the resriction is too much. Your also putting the warm air to the second rad. You lose effiency. Bad idea and not done in the WC world.
Your still sandwiching radiators. Still a bad idea.
Teach me how to drive please even though you haven't driven a car.
I appreciate your opinion Conumdrum and yes, I get the irony of one who has no practical experience of watercooling giving an opinion on the subject however,
it was an opinion, just that, if I was in that situation and had the money/stock lying around then that is how I would proceed.
on a physics level I dont see any problem with a fan pulling air into a radiator and another one on the other side pulling the heated air away, it seems a logical enough approach to me,
You have experience of W/c'ing and I respect that, and as and when I come to doing loops myself, I would most likely take your comments into account more so than other peoples.
I saw a question and answered it the best way I could is all.
