Impressions are good, little on the loud side when on extreme, cooling seems good, installation is improved but still very hard!
Software is a big improvement. More impressions, temps and everything Will come tomorrow
I can see the H100 out-performing the Antec 920 (which I have) by around 5c - with a considerably high OC.
In my case:
Here is what I observed - I did 5Gflops of IBT on each test:
920: 79c was its hottest core (this is with the SP120 quiet fans
1250: 70c with EXTREME mode selected and 75c with SILENT mode selected
As it stands, I would say that's a 4-5c improvement over my 920 - which is in line with the performance shown by the H100 over the 920.
However, I feel I can do better - so I'll be doing more tests and be removing the cooler and seeing if I can get a better thermal paste application on there and a better overall installation.
The provided software is a huge improvement and excellent.
I especially like how the RGB light can be adjusted with the liquid temps - meaning you can go from white to red on your Antec LED colour, simply off your liquid temps (it doe sit automatically)
I don't want anyone jumping to conclusions - that's why I'm going to do a variety of tests before writing and publishing my review.
An unboxing + installation guide will be published on YouTube soon - I'll also create a new OCN members club about it
More pictures - with a re-sitting. I decided to apply my own MX-2 paste - which coincidently I've now run out of, thus having to order some more. I ordered some MX-4 to come in
And yes the tubes are long enough to have it so that in my Fractal R4 - you can have it from the front.
The extra splitter I discovered during my unboxing is for you to have a pull/push config.
If I can get rid of my HDD back at the bottom, I'll do so and try and push/pull with some SP120's on the rad.
(I had trouble removing my bay as the screw was super tight and wouldn't come out, meaning it was rounding the srew, thus I need to find another screwdriver to get rid of my HDD bay in my case)
Applied MX-2 - pea sized dot - no change in temps (which I'm a bit disappointed about - as I was hoping for lower temps.
I'm going to now do a push/pull config with my SP120's on the outside of the R4 case
Went for the stock antec fans as they were 4pin PWM and they can ramp to 2.5k unlike my SP120s.
Getting ready for take-off
