merceless

the in port is on the right side. do u mean turn the block upside down?

bitfenix spectre pros, and i run them all as intake at max speed, atleast until i get this sorted then ill run them nice and quiet i should have plently of rads. if there was an issue with the rads not handeling the heat then i should be able to see that effecting cpu temps while i run unigine heaven or something (plus i felt the rads and theyre not warm). I should have also mentioned that im only running the one gtx780 atm, because the 2nd is in a 4x slot. that was my first thing i tried. I still think there is a possibility of contact issue though, but short of pulling the thermal pads off the ram moduals and just really forcing it to contact, i've tried everything lol. the loop order is cpu>gpu and it's all in correct order, plus i've tried switching the ports on the cards to switch flow direction, but no luck. not océd at all and the power limit is stock at full load (XTU) it doesn't exceed 65c, and that was oc'd at 1.3v. The rads are NexXxoS st30 full copper and im running Bitfenix Spectre Pros in intake. I'm also just running distilled water at the moment

Please help, im out of ideas. I'm running a 4770k and 2x gtx 780's (reference pcb) in a custom loop. The gpu blocks are XSPC gtx Titans (for 780, 780ti and titan) and i have quite high temps in benchmarks and general gaming that eventually reach throttaling point. Gpu's arent océd and i have pulled apart my loop and blocks to reseat and re-paste my gpu's about 8 times now. I've tried the thermal paste that comes with the blocks and some artic silver that i have (artic works slightly better) and i keep having high temps in the 80's to 90's within 30 secs in Unigine Heaven and also when im playing bf4. I've bled the system of bubbles (spent hours doing this) and also tried reversing the flow direction even though it's not supposed to matter with these blocks, and no luck. I've got plenty of cooling potential in this system as i am running 2x 280mm full copper rads and a Phobya DC12-400 pump (which i've run at 12v just to be sure). Is there anyone that has had a problem with these blocks, everyone i've seen using these have got load temps below 70c. I'm pretty thourough with my builds and i have just spent 42 hours straight determined to diagnose the problem and it's driving me nuts. I've attached a picture of the loop, order is; res, pump, front rad, top rad, cpu, gpu's. I am also aware that my bottom card is in the 4x slot, as i am waiting on a flow bridge and i decided to get this build started anyways Edit: i have run into a bigger problem about a day after i posted this, my motherboard wont post. ive decided to return the board and am going with a sabertooth mark 1. Until then i cant really test any posible fixes for the gpu problem 8/24/14: I have the new board in and running, still having cooling issues even with the xspc flow bridge ive installed. The second card is a bit cooler but still hits throttle temps in about 10 minutes when playing Battlefield 4. I've tried a few different things people have suggested but still no change. Could tubing ID have this big of an impact on temps? i have 3/8in OD 1/2in ID. Is there any issue with pump flow rate? This pump is capable of 800L/hour, that should be fine right? I havent tried the spread method with the thermal paste yet, does anyone recommend this on the gpu/s? FIXED: I found a thread on overclock.net that had a fix to my issue. What i had to do was carfully sand the standoffs on the block down a bit so the gpu and block would make proper contact. Had to do this to both my blocks, and now they dont exceed 40c in Unigine Heaven
