mondieu1724 Posted April 10, 2013 Share Posted April 10, 2013 I am so wretched! I have spent the past week trying to stabilize this system for video rendering. I purchased the H100i after noting that 4.6Ghz air cooling overclock on Ivy Bridge seemed the norm. Surely it would be easily realized with watercooling. But no! I can only stably achieve 4.4Ghz and even then temps are barely manageable in the high 80s C. I know it will still crap out in the middle of an hour long video rendering. I need the speed! I need return on the investment in what I thought high-end components. I have also reseated several times using ArticSilver5 in bean size proportion. I was confounded by the CorsairLINK not seeing the H100i at all; only earlier today gaining recognition by external USB port. Read these forums on the software issues; vomited and chose to wait for a software upgrade thinking the hardware was stellar. It is maddening reading these forums as they would give anyone pause in purchasing. I relied on techbloggers and their video reviews which gave naught but high praise in making purchase. In short, with fan speeds maxed in a huge case, I expected much better cooling. I am under the 1.35V power level and using CPU offset in the bios. Can't this device at least compete with an air-cooled solution? Must I delid the CPU to realize any benefit? I am wondering whether my pump is circulating sufficiently. In CorsairLINK, it reads 2178rpms. Is that normal for others? The H100i temp skyrockets to just under 40C on stressing the CPU cutting quite monstrously into the cooling delta. Is that normal?

wytnyt Posted April 10, 2013 Share Posted April 10, 2013 their test was done in a controlled situation so these are 'ideal' temps and not realistic in a user environment,least common sense dictates that to me.Oc'ing this high makes the cpu produce so much instant heat,nothing can cool it fast enough I relied on techbloggers and their video reviews which gave naught but high praise in making purchase. the reason for this is rather simple,they know their way around a computer and dont experience the problems of the average user Link to comment Share on other sites More sharing options...
panduhsaur Posted April 10, 2013 Share Posted April 10, 2013 Well, if you can OC at all, congrats, I can't overclock my ivy bridge at all because of the terrible paste on the die. You may have to do what I'll have to eventually do, which is delid your ivy bridge and then proceed to overclock. In the end its not the h100i, its your processor.

mondieu1724 Posted April 10, 2013 Author Share Posted April 10, 2013 Indeed, one more BSOD and you would know me by the trail of the dead! I spent all night researching and all the day implementing solutions. First: The mounting of the backplate on this ASUS Maximus (and apparently on many 1155 board) is simply not secure enough to assure proper contact between the heat transfer surfaces. The standoff screws lack sufficient depth to properly anchor the backplate to the motherboard. Without proper foundation, it is not possible for the H100i to be deemed well-mounted. I secured 8 3/16 x 1/2 x 1/16 rubber washers from Home Depot and placed them over the backplates standoff screw sockets. This afforded a proper immovable mounting of the backplate to the board. Now I at least had a secure mounting surface for the H100i. I also bought safety razors and denatured alcohol and returned to delid my i7-3770k. It took about an hour to delid and clean. I only had Artic Silver 5 thermal paste on hand but will order the superior Coolabratory Pro after I've time for more research as to its effectiveness. Once delidded, upgrading or changing thermal paste is child's play. I am pleased so far. Ran AIDA64 all afternoon at 4500Ghz and temps were a full 40C below my last effort which always bluescreened as temperature outliers reached over 110C prior to today's changes. Also did quick validation using IntelBurnTest and temps maxed out at 85. This was at 1.35V which I will now attempt to lower. Hopefully the combination of secure mount with rubber washers and delidding along with a thermal paste with a high heat transfer coefficient will get me close to 5.0Ghz OC.

Dave65 Posted April 11, 2013 Share Posted April 11, 2013 How can you say that? I have a Maximus V Formula and a 3770K at 4.6 ghz and I never delidded anything and my temps don't go over 74 to 80 with h100i cooling.. Link to comment Share on other sites More sharing options...
mondieu1724 Posted April 11, 2013 Author Share Posted April 11, 2013 Indeed, I now believe there is substantial headroom to go above 4500GHZ! In the 4 hours of sleep afforded me, I was able to at least validate by AIDA64 running at 4500Ghz with positive offset reduced to 0.005v, a Vcore of 1.27V which averaged only 67C. It would seem that undervolting at this high overclock has a distinct probability of success. As I simultaneously delidded and introduced rubber washers for proper mounting, it is difficult to attribute which had the greater impact but there is substantial literature supporting the efficacy of both. I have gone from self-flagellation and cursing my existence to happiness and a sudden yearning for blondes... If I am to run stably at 130% of the rated speed, I will feel somewhat future-proofed by the selection of components herein. Link to comment Share on other sites More sharing options...

mondieu1724 Posted April 14, 2013 Author Share Posted April 14, 2013 Running 24/7 at 4600Ghz on i7-3770k using bios offset. Premiere Pro, BF3 and Crysis 3 see only occasional spikes into the 70C territory. IntelBurnTest can spike temps upto 95C but that is at extreme severity and normal usage, as stated, doesn't approach the stress test extremes. 4700Ghz elevates temps to the 80C area with video/gaming stress but suffers occasional bluescreens as well so not stable enough for daily setting. Proper mounting using rubber washers for thin motherboards is an absolute necessity. Delidding (I will shortly remove the IHS condom and cool bareback) is also essential to reach stable overclocks unless you have a lucky chip. Mine appears to crave voltage for stability.
