[Martinsliquidlab.org] i7-2600K Koolance CPU-370 Review

post #1 of 7
Thread Starter 
Detailed Review Link

I've got the fine details on my site link above, but I'll summarize below:

Thanks to Tim from Koolance for supplying the test sample (CPU-370), this is my second in a series of CPU block tests I have planned for this processor.thumb.gif

Packaging

Short of barbs, the package is extremely complete for both Intel and AMD users. I personally tested both nozzle plates for restriction, but decided to go with the 1.5mm nozzle for my first round of thermal tests since it was still fairly low in restriction. Overall, I was very happy with the packaging & parts package…all you really need to buy separately is a set of barbs.

External

cpu-370-8.jpg?w=614&h=602

Overall the exterior inspection/review was a bit hit and miss. The overall materials are very good, but I think there could be some improvements to the hold down plate finishing and improvements to ease of use on the hold down system.

Internal

Overall, the interior is exceptional in quality, fit, finish, and attention to detail. I would suggest taking the block apart and swapping out the nozzle plate to the smaller 1.5mm option, but feel free to experiment.

Restriction

In general the Koolance CPU-370 is average to average/low in restriction compared to the wide range of various blocks tested. Compared to the previous EK Supreme V1 tested on this processor, it is substantially lower in restriction (less than half as much pressure drop). This means the block will serve well in a wide variety of pumping and multiple block configurations without causing too much restriction…very good!

Thermal Performance

cpu370-therm15-comparison.png?w=560&h=540

cpu370-therm15-flowrateeffe1.png?w=588&h=665

Overall, I was very pleased to see the advancements in performance of the CPU-370 over the old EK Supreme V1. Koolance has managed to produce a block that has half as much restriction, it performs better by a few degrees, and is also a very strong performer at a variety of flow rates…excellent!

Conclusion

The block is an excellent product and performer, it does have some minor areas of improvement in finishing of the hold down plate and mounting mechanism ease of use, but otherwise excellent. The CPU-370 is a well tuned balance of lower restriction and high thermal performance that performs in a wide array of mounting systems and pump/block conditions.

Pros
  • Extreme Thermal Performance, best to date! 3C better than the EK supreme V1 (note this is the OLD version supreme,not the HF)
  • Very good average to average/low restriction. Highly compatible with various pumps and multiple block loop configurations.
  • Extremely complete package with heavy duty back plates and hold downs for both Intel and AMD processors.
  • All metal heavy duty construction ensures long term durability.
  • Nickel finish prevents copper/brass oxidation
  • Machining perfection (extremely high quality machining work and fitment).
  • Unique shape/visuals (not just a square or ordinary block).
  • Multiple nozzle plates to meet varied needs

Cons
  • Nickel finish on hold down plates are not smooth (textured like finish).
  • Loose mounting mechanism is more difficult to use for beginners and may create more variable mounting results.

Performance wise I couldn’t be happier, the attention to detail in the areas where it really counts is above and beyond. I had to get picky about the few areas I could find for cons, neither of which was heavily performance related.

Cheers!cheers.gif

Wow, great review!

Looks to be a good performer, I'd probably take the EK for looks however smile.gif

Thanks!

Make sure you understand the supreme I used was VERSION 1 not the newer HF model. I have put in requests to try one of the newer HF models though and hope to get a chance to make that comparison later.

Ahh, I see.

Doesn't retract from the point that it's a great review.
