the shut downs were from an unstable OC on CPU I am now a official owner of firstname.lastname@example.org and email@example.com and unadulterated by a block and hammer
I never had this happen with my 2500k it was always BSOD so this set up was kind of new to me.
I put my finger on the vrms they didn't feel too hot remembering I have 200mm and 140mm fans blowing directly onto my GPUs I feel they will be fine.
That's why I nick named my PC kamikaze and it will die an honorable death smashing some benchmarks
I had a look at your pic when you said about putting heat sinks on the memory and posted some results
Here is my original water loop with my now dead GTX 580 lightnings I decided to put them under water because they sounded like jet planes flying over the house on hot days so I couldn't justify 680s 7970s had bad drivers. I was happy with the 580s so I got universal blocks knowing titan was on the coming. That idea went out the door as soon as I heard the price.
I got a full refund from MSI for the 580s so got the 770s as I couldn't justify the price premium for 780 or titan or 690 so went for bang for buck.
so having all this water cooling gear sitting around just seemed the natural thing to do and same with the hot wire.
But if I didn't have this water cooling gear sitting around I wouldn't have bothered with water cooling for the performance gain.
I would have spent the extra money on 780s if performance was my goal.
I have always been a tinkerer when I was 3years old my Mum left a screw driver out I got up early and by the time she woke up the TV was in pieces
I just cant help myself when it comes to modifying for added preformance
