you might be right about fans though they are pretty loud and dont push a lot but i was told with these radiators that you dont need pressure fans for them as the fins are not as compact... or dence....

might try adding another 4x 140 fans to both radiators

as currently the radiators are 480mm on top with 4x fans only in pull configuration
and the bottom rad has 3x 120 under the radiator in the pull configurations

no fans on the other side of the radiators

you might be right that im not getting the air out of the radiators fast enough hmm food for thought lol buy more fans tongue.gif

well guys i work nightshifts so i have to go now but i will check up on replys to any idea`s you guys have will also here is a video of my system, ignore the light show as i just got them at the time and need to configure them lol

though the video is with my 2x980TI`s though everything is the same apart from the cards replaced with 1080ti`s.....

also the res is only half full, hahaha its completely full now smile.gif

High static pressure fans are a must.

If you lay a sheet of paper on top of the roof of your PC (above the radiator) does the sheet of paper float or blow away? It should. If it doesn't you're not getting enough air through.

I'd say this is even more important with thick radiators.

The highest static pressure fans I've ever seen/used have a static pressure of 7.63 mm H20. And are capable of spinning up to 3000 RPM. (and moving 186 cubed metres of air every hour).
(Noctua NF-F12 industrialPPC-3000 PWM).

For comparison, the Corsair SP 120's (also high static pressure) are 3.1 mm H2O).

Also, sometimes radiators benefit from a really good cleaning (dust removal).

2-3C diff maximum at full load. With Kryonaut and EKFC GPU block my GPU-water delta is about 9C under full load with 225LPH flowrate.

Recently I tried out the Noctua 140mm industrial and it's pretty crazy. Moves 269,3 m³/h air and 10,52 mm H₂O. It's pretty silent at low RPMs and can idle at 0 RPM, which is nice.

Something different to save some power and to lower temperature is to use a framerate limiter like the one from Afterburner. Especially for SLI systems, this also often minimizes micro stutters and gives a better gaming experience than unlimited.

If it's all about airflow (252.85 CFM) and static pressure (35.865 mmH2O), you could check out https://www.newegg.com/Product/Product.aspx?Item=N82E16835706015

I had two of these in my case at one point, but I'm down to one now. I have run them both at 12V and 5V, and at either voltage, have no issue keeping my CPU Kraken AiO cool. Fair warning, they're loud! LOL

I'll second Noctua here. I had some initial issues until I discovered a noise that was occurring was because of a daisychained fan.

I got the Noctua NF-AF14 industrial PPC-2000 PWM fans for my radiator. I grabbed these because the 3000 go way beyond reasonable volume and my Kraken's pump speed is dependent on the fan speed.
http://noctua.at/en/nf-a14-industrialppc-2000-pwm

A simple fan curve keeps these incredibly quiet, but they have the horsepower to push some real air through the radiator if necessary. My PC runs at ~40dB including all ambient noise around me even with these fans (jumps to ~48dB if I'm pushing the CPU hard).

Hey peeps, been busy with real life stuff, haven't been ignoring you all.

Will get caught up soon. ph34r-smiley.gif

yeah, after switching to Noctua F-12s, .... I'll never go back. They put all fans Ive tried before to shame.

It's the best paste that I've ever used. But you are probably talking 2-3 c drop as others have said provided that the factory Tim job was good. Otherwise it might be a much bigger temp difference. I believe Slack saw a pretty big difference.

Got another STRIX today. It is even worse than my current one. Won't even do stable 2012 with simple OC in Heaven.

If it wasn't for this site you wouldn't even care about it. Mine can hit 2100 with enough voltage and be stable in anything from benchmarks to games but because of power limits I've decided to keep it quiet and cool at 0.925mv and 1936 core clock thumb.gif
