    Heatkiller 4 pro verses Opimus cpu block first post 4 for EK blocks


    Hi,
    Been some buzz about these water blocks and a not so great review on techpowerup only showing a meager 1c better on their testing results

    Optimus Foundation CPU Block (Intel) Review | TechPowerUp

    Optimus Signature V2 CPU Block Review | TechPowerUp

    I altered my signature demo block a little because it wasn't making good contact with the top of my chip it had just a little too much bow and I wasn't getting very good results but if you look at the image where the scratches are on the block that is where i lapped it down a little so the bow would be reduced.

    It does work well now but as said I had to alter it's bow so results are not what someone else might find.

    All I have is testing with the 119.us foundation block which is pretty impressive at higher clocks way more than 1c

    4.5 was only about 3c better than the Heatkiller 4 pro copper/ plexi
    Used static mounts on the HK 4 pro as well to keep things as equal as possible that plus the HK 2066 mounts aren't very good 1151 socket they use conventional studs/ springs and nut
    2066 they used a bolt/ spring and washer so talk about awkward to keep a cpu block centered while mounting it :/

    I had some extra bitspower summit mounts that worked pretty good for this purpose for HK I was using a ek evo water block mounts prior it was more conventional system but thought I'd use static mounts/ no springs just as the optimus blocks use.

    Max core temps speak for themselves on how well the foundation handles high clock temps
    Added some little water block images to show the blocks rotation for that test

    HK 4 pro likes goofy mount where as foundation likes and is designed for normal mount
    Optimus foundation kept hottest and coldest cores within 10c of each other where as HK 4 pro looses it past 4.5Optimus Foundation and SigV2 verses EK Magnitude cpu water blocks-heatkiller-opimus-blender-long-4.5-1.24v-optimus-winner-3c.jpg

    Hi,
    Little teaser of a EK Magnitude I received
    Of course I sanded and polished the nickle off the top because I like the steam puke thang

    Testing still going on not looking good for the magnitude just against the optimus foundation :/
    Should have everything finished Sunday night

    Hi,
    lol yeah love them
    Couldn't take it anymore had to polish the ek cold plate it was too tough to get all the thermal paste of it not perfect but damn sight better

    Hi,
    Well here is the SigV2 verses black acetal ek copper nickle wasn't all that different 1c one way or another 4.5-4.8 and also foundation and ek magnitude nickle top

    Core temp spread shows mount is pretty good near if not at 10c apart from min max core temp spread

    SigV2 clearly is doing a lot better and 6c cooler at 4.8
    This is a modified SigV2 original didn't fit my chip all that well so I adjusted it's bow similar to the way ek uses shims to adjust their bow except I had to use sand paper so it was a little more difficult image shows where.

    Room ambient 77f degrees average 76-78f degrees a/c on-off
    Water temp max 34c
    Fans full blast 8-ML140 push/ pull as well as 2-D5 pumps images are in system spec's along with gear list x299-9940x

    Loop order
    EK D5 pump reservoir combo/ 280 GTX rad/ vrm block/ 280 GTX rad/ EK D5 Top/ CPU block/ GPU block.
    Thermal paste hydronaut

    Plan to retest both ek blocks again but as I said core temp spread 10c or within usually shows good contact.
    I'm using 1.25v for 4.8 and avx offset to lower clocks to 4.7-4.6-4.5 to see how well these block handle voltage
    Obviously I'm not trying to find least amount of core voltage for each clock only least needed for 4.8 and stay stable enough for these tests

    I'm also outlining effective clocks and max core temp on images and blue highlighted is coldest core
    Blender Opendata long test is used freeware anyone can use it.

    Hi,
    That is what I stated and it's what the temperature images show too so yes
    Optimus SigV2 6c cooler at 4.8
    Optimus Foundation 4c cooler at 4.8

    Both optimus blocks 50% cheaper as well
    Nickle version of ek's is actually 300.us+ you could buy both optimus blocks for the cost and shipping of one ek magnitude nickle lol

    Have you used the Velocity Plexi? I'm thinking of getting it.

    Hi,
    Nope but I'd get a heatkiller 4 pro before getting a velocity both out of Germany
    Heatkiller is likely cheaper and better.

    Hi,
    New test
    Polished the copper cold plate on the ek mag nickle
    SigV2 still 3c cooler at 4.8 though but did do well 4.5 & 4.6 but lost it at 4.7...
