That thing is super impressive. It would be awesome to watch movies against the wall in the backyard while in the pool. Perfect for summer nights!

I did Intel Burn and Memtest.

Ever since someone mentioned my flow I'm concerned with tube #2, the blue tube. That is the one that feed the CPU block. I know you said you don't watercool, but perhaps the pump is working too hard against gravity to get to the CPU block on that tube.

Here is a picture of my loop order: http://i.imgur.com/aScGNQL.jpg There is another radiator above if you couldn't tell.

That was during Intel Burn Test on high stress with 10 passes. I'll post a picture of my loop in just a bit. Now that you've mentioned that I think there could be an issue in my loop setup.

GPUs are also watercooled, two rads. I'll post pictures of my loop in just a bit. I'll inspect for wiring causing it, but I don't think its that because it only happens in demanding games.

I haven't OC at all yet because of this issue. I was running on a Corsair 850, but just bought this 1000W about a week ago because of this issue. Here is a screenshot of HW monitor. http://i.imgur.com/xSVZbDy.png

Playing GTAV and Dying Light my PC has been restarting itself. Sometimes I can play for a few hours, other times it happens within 20 minutes. I haven't had this happen in any other less demanding games such as Diablo III, Heroes of the Storm, or Team Fortress 2. I just completed my first watercool and want to make sure my temperatures are okay and that is not what is causing the restart. i7-4790k, GTX 980 2x SLI, 16gb Ram, Asus Maximus VII Gene, Corsair 1000W PSU, Windows 8.1 64bit. CPU idles at 26-30C depending on ambient temperatures, which have been 73-80F. Underload the CPU is around 50-65C depending on the game. Are these temps too high? I've tried reseating the CPU block, applying new paste, etc, but I've had no luck. My GPUs don't get over 50 in any game and idle around the same as the CPU. Watercooling parts are: CPU block http://www.frozencpu.com/products/19630/ex-blc-1445/EK_Supremacy_EVO_Universal_CPU_Liquid_Cooling_Block_-_Acetal_Nickel_EK-Supremacy_EVO_-_AcetalNickel.html?id=2T5sPcix&mv_pc=159 and pump http://www.frozencpu.com/products/21018/ex-pmp-247/EK_DDC_X-RES_Top_100_w_32_PWM_Pump_EK-XRES_100_DDC_32_PWM_incl_pump.html?id=2T5sPcix&mv_pc=158) Perhaps it is also worth noting that I am using a Case Labs Mercury S5, so my PC is mounted horizontal, opposed to the traditional vertical. Are my temps okay? Should I perhaps try a new CPU block, or is it a pump issue? Thank you guys for any help.
