This is my hard-line water-cooled build in a Corsair 460x, in this build I have done three things that I have never done in a computer build before;
- Delidded and relidded the CPU.
- Individual sleeving of wires and shortening and recrimping where required.
- Custom hard-line water cooling, which is the first water-cooling I have done outside of an AIO cooler.
It’s named after the blue glow visible during Cherenkov radiation. Many mistakes were made along the way but I am very happy with the end result.
The i7 7700k has the highest single core performance of any CPU according to passmark (at time of purchase), as this is a gaming build this was important. It has a thermal problem, however, out of the box it was idling in the high 30’s to low 40’s and highs of 80-90°C, I reduced the Vcore from 1.3 to 1.2V which somewhat helped the problem but I was still getting temperature spikes and random increases of fan noise.
So I used a deba8er delidding tool from overclockers.co.uk to knock the IHS off and cleaned the old paste off replacing it with coollaboratory liquid metal ultra on the die and then used loctite RTV black liquid gasket which I had left over from fixing my car to glue it back on. I reassembled everything back to how it was and retested and reduced the idle temperature to the high 20’s to low 30’s and testing with Intel tuner, max temp after testing for an hour was 71°C. The above temperatures were taken while using an old Corsair H100i. (Apologies for no pics of delidding process my phone gave up on life half way through this build). With the water cooling at stock clocks and 1.2 Vcore it maxes out at 68°C and after overclocking to 5.1GHz at 1.32v and still idles in the high 20’s to low 30’s but it can spike to 81°C under load, which I can live with considering the extra performance.
I started out with some corsair LED sticks which you can see in the early pics but changed my mind and got the Gskill trident RGB which are much nicer.
I got a Samsung MZ-V6E250 as the main boot drive which is insanely fast and now makes me the slowest component in my set up. I wanted more SSD storage so I got a CT525MX for an extra 525 Gb of storage and I also put in my Corsair neutron 240gb SSD from a previous build. And if that isn’t enough storage I also have my NAS which you can see here: pcpartpicker.com/b/cH3bt6
What I needed was PWM, High static pressure, 120mm and ASUS Aura sync RGB compatible fans unfortunately no fans like this exist on the market so I got three of corsairs HD120s which gave me most of my requirements and then modified them using a RGB 5050 non-waterproof led strip (waterproof version won't fit) and soldered the original wire to them and then I modified the original splitter in the 460x case to work with 12v and the three grounds for RGB. They now have twice as many leds than before.
Edit: Ok so if anyone is interested Ive redelided the 7700K a second time now (three times in total) and used thermal grizzly conductonaut instead of CL liquid metal ultra not sure if that makes any difference but the application tools made the job a lot easier temps are now at a max of 67 deg C at 5.1Ghz @ 1.28 Vcore. I think the problem i was having was using too much silicone sealant for the IHS and it caused a larger gap between it and the die
Great CPU with thermal issues limiting overclocking potential, not good for a K-series processor.
Excellent board with good features and a pair of M2 slots and aura sync to control RGB lighting. Just wish it had more temperature sensor headers and fan headers as well as a way to turn off the motherboards RGB when shutdown.
Fantastic RGB sticks that have 5 individually controllable LED's per stick very nice looking but expensive.
Stupidly fast even for an SSD.
Nice high capacity SSD with fast speeds and enough storage for a lot of games and programs.
Great card, very powerful card very high stock clocks and great looks. Great thermal performance with original cooler not running that much cooler on water. Got an extra 200Mhz on the core clocks and no higher using water cooling, although some games don't like it despite extensive bench-marking at this speed so usually stick with 150Mhz extra.
Very pretty case with frugal cable management room behind the side panel, even so I got everything to fit nicely without bulging. In hindsight I should have got the non RGB version as without software control you only get a choice of 7 colours including white on the fans, also they are not PWM so they weren’t very suitable as my radiator fans.
Old PSU from previous build that was going to be used for an SLI setup that I never got round to doing, way more power than I’ll ever need, it’s served me well.
