Replace Fuzion v1 with EK Supreme HF?

[Kinsy]

Old setup:-

E6400 @ 3.6ghz 1.55v
8800GTS 690/1000
EK 8800GTS block
Fuzion V1
Thermochill 120.3 rad w/YSTech 120mmx38 fans - 135cfm and not quiet
DDC Ultra & Bayres
1/2 ID tubing & barb fittings.

I've recently updated the hardware after 4 years of duty without even emptying the water loop; I just removed the 8800GTS block and topped up the res. Running a 2500k @ 4843mhz 1.44v which hits max 63deg on core2.

I've got some new stuff to fit into my WC loop - EK 580 DCII block for my Asus GTX570, an XSPC DDC Bayres to simplify my loop a bit, a load of 3/8 compression fittings and 3/8 tubing. While I'm spending money I don't have I was considering upgrading to the EK Supreme HF.

The rad is cool to the touch at this OC at the moment even when priming - I'm definitely at the thermal transfer limit of the water block. Will the Supreme HF be too restrictive to run my GPU too? Looking at reviews of the Fuzion V2 I know the Supreme HF is probably even more restrictive. Worth me spending £50 for a 2-3deg drop dya think?

The supreme HF (high flow) is one of the least restrictive blocks out, think it's only just been bettered by the xspc raystorm. You'd see an improvemnt in temps over the fusion but finding any data for a comparrison is difficult as its a fairly old block now.

Yeah I've been struggling to find any comparisons. The nearest I can find is the Fuzion v2 VS the original Supreme. Some saw only a 2deg drop with a massive reduction in flow.

After a bit of research (mostly on old Quad core E6600 chips) the consensus is:-
The Fuzion v2 outperformed the v1 by 2-3deg;
The V2 had the option of a quad nozzle which helped drop the temps another 1-2deg;
The EK Supreme beat the Fuzion v2 in single loops by 1-2 deg;
The Supreme HF has up to twice the flow characteristics of the Supreme; plus it's quoted to be 'up to 3deg cooler than the Supreme';
And my radiator is very cool to the touch, I just bought the Supreme HF

At the very least based on that math, I will see a 5deg drop. Obviously since I'm plumbing the 570 into the loop it might not be so much, but we will see.

Also all the blocks will match being EN nickel with plexi tops
