cpu and water temps

[Nurf]

Hello everyone at OC3D!
This is my first post and I thought I'd start out by asking:
In a water cooling loop when cpu load (and thus heat) is kept constant, is cpu temp - water temp constant?
I've understood that it is but have a hard time believing that if I get for example 70 degrees load temps with water at 30 degrees, that would mean that the water would have to be 50 degrees to get the cpu to 90 degrees.

Now the reason I ask:
With water temps I'm thinking something under 10 degrees above ambiant so dropping temps 3-4 degrees without adding rads means way noiser fans. So if I'm happy with my temps but was able to drop cpu load temps by 3-4 degrees by upgrading my water block and TIM, that would let me raise my water temp by the same amount, making me be able to run my fans slower and getting a much more quieter system without having to think where the hell can I fit more rad.

Is my logic flawed?
(no need to speculate if my block can be so horrible that temps can be improved that much with an upgrade. I believe its possible and if im wrong, I shall learn it by trial and error :lol

the calculations are good. the reasoning is partly why we cool with water.
depending on load (app or synthetic benchmark) yes, the less load should mean
less temperature. and round-robin able to lower fans.

but truely, a load is pretty much balls-out cranking 150-300watts of heat. and
this is plainly more than 10° above ambient temperature.

if using an air-cooling device and the control of temperatures holds at under 75-80°
most won't consider water-cooling due to cost and complexity. but enthusiasts that
want the nth power and temp control will use water-cooling. the delta is close
to correct. many factors like fans, fan speed, radiator contruction and dimensions,
intake and exhaust temperatures and flow....

finding 2°-3° via waterblock or rad construction really isn't a bugger, mainly a
look or presentation. make-up in fan/rad usage.

primarily, low temperatures, low noise-quaility, and tidy looks are my soul
goals on water-cooling. others may concour or disagree...

Yup. Thats my reason also.

Thanx for the replies.
I'm updating my first wc build because I see too many mistakes in my work (mainly looks and noise) but even though its a simple plan and for you guys nothing that great, I can't use alot of money on something that isn't a necessity right now so timewise its my own orca. This gives me plenty of time to overthink everything and come up with questions like this :tongue:
And yes, I water cool for the fun of it, otherwise there would be no point in using money on this upgrade.
