I thought I had a reasonably stable overclock, a little disapointed my CPU wasn't in the top ten percentile... but not bad for a 2"er.
So i was happy.
Then I discovered Twitch Streaming and started using my other PC as a video encoder. After about 30 minutes, this turned into a bad idea... choppy gameplay and World of Tanks crashing all the time.
After some investigation, I found overheating was the problem, my 780 Ti was getting far too hot!
Delpy's words rang in my mind... I could just get a new 980, it runs faster and cooler... everyone wins! No. It might be the H440 with it's excellent noise suppression.
I bought the NZXT H440 from him on the 'cheap' as part of a 'bundle', it seemed like I was buying half of his PC since he was well on his way to Quad Channel DDR4 and exciting 4K gaming. His box looked gorgeous in white. I took it. And I have loved it.
So I bought a Corsair Carbide Air 540, since it was the case I had been experiencing strange longing for through googling on the interweb. Also in white. Not as cheap, but it's progress. I'd noticed the CPU was throttling during a 'Small FFT' test in prime95 and I wasn't in the mood for buying a better water cooler and most likely going down the custom coolage route. Those water blocks seem to cost a fortune... and I might as well worry about the VRM too, not having a clue about water pumps and fixtures, the answer really was 'New Case'.
I've got all the bits in the box and have waited a day for the TIM to set before running preliminary benchmarks. Its good news! No more CPU Core throttling, the 780 TI seems to be enjoying itself! I haven't got so far as to test it with the streaming but I've been busy... Since I was shopping for PC bits and with GTA V reportedly costing 60GB of storage space I threw cats to the tigers and bought another SSD. So now there's a 480GB SSD RAID 0 setup in there. I spend the evening laughing even harder as I spent 10 seconds longer watching Communist Russia load into a game of World of Tanks.
Now it's time to cool! The fans have been plugged in... and they work... and the case is damn noisy compared to California's Finest, the gloriously well built and quiet NZXT H440, but I'm happy with the results so far. I haven't even adjusted the fan profiles yet. It seems to be cooler, I might as well clock it harder!
Here are some pics of the temps I'm getting.
Aida64 Stability Test + Furmark GPU Stress Test
H100i in Quiet Mode
About 22 minutes.
prime95 small FFTs
H100i in Performance Mode
About 10 minutes, and another couple of minutes after a BSOD reboot.
The chip is a 4770K clocked to a permanent 4.6Ghz @ 1.322V
4.3Ghz Mem Cache with 8GB of xtreem Team 2400Mhz DDR3
Plugged into an Asus ROG Maximus VII Hero.
H100i with 4x Noctua NF-F12 in push-pull as an exhaust in the roof.
I don't really know much about how to squeeze more hertz from the chip, the different styles of voltage manipulation etc. Now the chip doesn't thermal throttle at 4.6! I'm guessing I could maybe push 4.7, 4.8? Should I be using adaptive voltage? Also raising the Memory Cache speed, should I be benchmarking each increment as I noticed this doesn't change perfomance much. I've heard that Prime95 small FFTs are a little overkill for stress testing? Is 3dMark the best way to test clockspeed changes for perfomance? What's your guys take on it?
The Gigabyte GTX 780TI Ghz Edition is stock, should I be remounting the heatinks with better TIM before I overclock it by the 80Mhz it can probably handle? I read the temperature of it can decrease FPS due to the auto throttling of power that it does... have I heard wrong?
I haven't switched any fans around or messed with profiles, but I'm wondering if the case will be quieter... because it is like a subway station compared to the h440 (it's not really) Maybe with 3 noctua 140mm fans or perhaps three 120mm fans in the front? I've taken out the three and a half inch Caddys from the floor and with a little angle grinding they could probably seat some more fans.
Should I ditch Corsair Link software and get better range of control over the Noctuas on the H100i?
Is positive air pressure what I should be looking to create?
