Alright, thanks. I wasn't sure whether above 1.2v was super high for Coffee Lake R or something so I stayed way below that.

I really want to overclock my 9900k but don't know how far I should push the voltage.

Not a super high overclock but what I think is impressive about this score is how high I was able to get with a 4790k @ 4.7ghz core, 4.3ghz cache. Also, if memory matters in the score, my kit is the HyperX Fury 2x8gb @ 1866mhz.

I don't really know much about car radiators but it seems like it would be safer to use one made for computers rather than a car, but if you think it'll work go ahead. And about that small power supply for gpus, you could try something like this, https://www.amazon.com/dp/B06ZXQRTQD/ it is fully modular so you wouldn't have any extra loose cables.

So why isn't using a normal radiator designed for pcs an option?

Probably around $250-$300

I would just get a 1070, I use one in my build and get above 144 fps max settings in pretty much all games including PUBG, CS:GO, Rainbow 6 Siege, Battlefield 4, Rocket League, Warframe, and pretty much any other game I play.

I'm fairly new to watercooling and this will be my first custom loop. I want to keep my 4790k and gtx1070 in the low 30s at idle and low to mid 60s at load. I do plan on overclocking the 4790k to 4.7ghz maybe 4.8 and will also be overclocking the 1070. I really want this to be a silent build so I got the quiet sp120s and the PR22-D5 for its speed adjuster. If any of you have recommendations on how I should mount things in the loop please let me know because I want to to look nice too, I'm thinking about getting a separate pump/reservoir so I can put the res more on display. Thanks! Below is how I'm thinking of setting it up
