Edited with new info.
Hardwaremax reviewed the Heatkiller IV Pro. Will have to wait for more detailed breakdowns from guys like stren but very nice results:
Test system is a 5960x at 1.3v on a Rampage V Extreme. http://www.hardwaremax.net/wasserkuehlung/wasser-kuehler/1085-test-watercool-heatkiller-iv.html
Comments from the review, auto translated:
Build:
Processing is at our test subjects in the copper, nickel and acetal version at an exceptional level. The cooler act as a unified whole and give absolutely no reason for criticism. Also, the haptic feedback of the cooler is unique. Like a precious stone embeds the nickel version in our hands. No sharp edges, no faulty nickel, to ensure no poorly cleaned or polished bodies tarnish the image. No matter where you throw his eye, it is only of absolute perfection.
Design:
Under the hood, it goes positive. Here, too, worked exceptionally clean. A nozzle plate in the conventional sense Watercool has however omitted. A similar construction is located now fix a pedestal in the lid of the cooler. Also striking is the increase in the base of the cooler. This increase is 0,075 mm and ensures better downforce. Also noteworthy are two small seals that ensure a targeted way to transport the water in the reservoir.
On flow:
Also our assumptions reflect the flow measurements. The acetal Basic version is due to the smaller number of sipes with about 223 liters of flow per hour the first place. The Pro versions still have enough flow to play with up to approximately 213 liters per hour. Basically, the result is better than expected, as the fin density of the two bottom panels has failed high.
On heat dissipation:
Here again confirm our suspicions. The slightly more cooling fins provides a minimally better result the Pro version. The nickel version manages nearly in the first place, closely followed by Phobya UC1 Extreme and the HEATKILLER® IV in the copper version. But the acetal Basic version is reflected in the upper third and precipitated by a good performance. The differences would appear minimal at first sight, in comparison with the XSPC Raystorm, EKWB Supremacy Evo or the Koolance CPU-380 but the differences are somewhat larger.
As the review says, as with anything Watercool quite frankly, it's heavy as hell and flawless in appearance and feel.
Only 4 screws:
Close up look at inlet
There is no jet plate in HK IV. Hardwaremax shows pix of the innards so I don't have to bother taking this apart. The IV Pro has 78 fins:
The basic version has 49 fins:
Technical data:
I ordered the 115x backplate also and the design is changed from HK 3.0 version which looked like this
to a very plain looking this
They widened the spacing between the ports from the HK 3.0 so it should be able to take bigger fittings more easily now.
Mounting is "error-free" -- there is a stop on the post so you just screw down the spring until you hit that stop. No messing with calipers like in HK 3.0. Mounting pressure is 220 newtons. Watercool says orientation makes no difference.
This is the all copper version obviously, also comes in nickel plated, anthracite nickel, acrylic, and acetal
There is also a Heatkiller IV Basic which is cheaper and promises roughly HK 3.0 performance. Comes in acrylic and acetal
Not to be racist but I love German products. There's a characteristic quality there that I just adore. Had to order this directly from Watercool since Aquatuning is the only place that even lists it and they're a few weeks away from being in stock. Backplate was 6.68 euros, block was 67.18 euros. Oddly they charged me less than the price they list on their shop which is 79.94 euros.
