Rad thickness = Perfomance differences?

[Mick Naughty]

Have my first build up and running for two months now. Just added a second card and had to move my pump to the back.

 

Looking to seeing if its worth getting some rads that fit in the air 540 before moving the rig over to my core x9.

Currently have a 280 80m and 360 60m I think. Gonna  try a slim ek 360 and prolly get a 40m 280 rad and prolly put a 140m rad on t he back.

 

Wondering if people have changed rad thicknesses and noticed any temp differences what so ever?

Just trying to get an idea of how the next build will go or if I can finally get all this crap to fit and close it up instead of looking like this.

In theory it should improve cooling, more surface area = more heat dissipated out.

 

I can't give you any real world figures though

In general thicker rads will give more cooling with the extra surface area but is far less than say just getting a longer rad as they tend to perform better than an extra thick one. This from Daz goes over it quite well:

 

[Enderman]

thicker rads are not much of an improvement as dazmode tested out

larger area (140mm vs 120mm) and large size (360 vs 240) makes a much bigger difference than fin density and thickness

 

you get a more significant difference when running extremely high rpm fans though

 

i would recommend black ice radiators for your next build, their performance is very good especially with slower fans, great for silence

[Jidonsu]

Thicker radiators pay off the most at higher fan rpms.

Perfect. Just the info I needed. Feel comfortable about swapping these giant rads out now. Just hope I can fit 360 and 280 in it still.

Any graphs like that comparing coolants? Im on distilled water right now. Had ek fluid but I've been chaning so much that it isn't worth the cost.

 

Right now all the fans and pump are pegged at 50% Keeps the temps and sound levels where I don't mind.

Only real concern now is a fan controller. Was looking at trying out the grid. At some points my channel headers will cut off. Not sure if its age or all the power draw with the oc and 5 2k rpm noctuas.

Between different fluids they are fairly similar throughout there distilled water still tends to be the best for heat transfer, where you may see a small increase in performance with nano fluids like from Ice Dragons or to a certain degree with Mayhems Pastel as they are formulated from Ice dragons. 

 

For fan controllers if your using PWM based fans your motherboard is usually your best option with a power splitter and only using the control signal from the motherboard to vary the speed of the fans.

Already had one header short out. With the inconsistencies im having with the mobo controlling the case fans id rather get a pwm controller. The cpu and cpu opt header's are fine. These noctua fans seem picky. I keep them at 40% and if theres a lot of draw, say from the cpu and its oc, the fans loose a bit a power for a second and then cant get back started.

 

Would like a powered splitter of some sort. Don't wonna monitor fans anymore.

As long as they are PWM fans a power splitter may be your best option as it doesn't take power from the motherboard, if your directly power them off the motherboard a good rule of thumb is 3-4 fans per header or less if they are fairly high current. 

 

Something like this should do the job quite well: http://www.performance-pcs.com/swiftech-8-way-pwm-splitter-box-sata.html

Ill have to order one of these and another rad here soon. Gotta settle some identity fraud first.

Is your board a Gigabyte by chance?

Edit: Nvm just checked your profile. I had the same thing happen with fan headers on a Gigabyte board.

Yea, Asus board. But I can see the rpms dropping of while gaming and sometimes the fan doesn't stop but the other times I look over at my pc and they are stopped. cpu and cpu opt headers never do it so I guess Ill have to get a hub. Really wanted my fans to be slower then the pump though.
