I sold the motherboard and processor of my main gaming PC last month and didn't want to upgrade until AMD put their cards on table, but my hand has been forced as I need to build up a new 'showcase' system for a meeting I have next week.
The timing isn't great with Ryzen on the horizon, but I wanted to build a system that provides the best compromise between performance and noise. I chose the Intel i7-7700 which is currently the fastest gaming CPU with a TDP up to 65W, an MSI B250i Gaming Pro was picked as overclocking is not required to keep heat down, the MSI board is one of the cheapest 200 series boards currently available but has a nice set of features.
Full System Spec:
- Intel i7-7700, 3.6Ghz Quad Core (65W TDP)
- Gigabyte GTX 1070 8Gb OC ITX
- Noctua NH-L12 Bottom fan only, down draft (66mm Height)
- MSI B250i Gaming Pro AC
- 8Gb DDR4 2400Mhz Dual Channel RAM
- Samsung PM951 M.2 NVMe SSD
- 500Gb 2.5" HDD
- Prolimatech Ultra Sleek Vortex 14 System Fan
- LZ7 Case with Cyclone Vent Panels
For CPU cooling I would have liked to have gone with the Scythe Big Shuriken 2 again, with its 10 heat pipes and 120mm cooling fan, but it was out of stock at my local shop! They did however have a Noctua NH-L12 which is renowned for being an excellent and quiet LP cooler.
Removing the top fan of the Noctua NH-L12 results in a cooler height of 66mm, 3mm shy of the LZ7's maximum CPU clearance. Online reviews show that even with just the bottom fan this is quite a capable cooler and exceptionally quiet, so I thought I'd give it shot, especially considering that low noise is a primary objective.
Unfortunately I was not able to install the cooler with the fins running perpendicular to the side fan which I was hoping to do, the 92mm fan mounted under the heatsink fouls on the RAM modules. This only leaves 1 possible orientation to install the cooler without it overhanging the motherboard edge:
The heatsink clears the Corsair Vengeance LPX RAM with a bit of room to spare, the fan is set to pull air through the heatsink (default orientation):
Motherboard installed into the case, looking good:
GTX 1070 installed, you can start to see all the clearances, it's going to be a tight:
I felt that the NH-L12 heat pipes were sticking out a little too close for comfort to the backside of the GPU, the gap was about 2mm. I slipped this ram module packaging tray over the end of the heatsink to provide a shield, it fit perfectly:
Power supply installed, not much wasted space in this build! The free space in front of the PSU is essential for cable routing with this modular SF450:
A small rubber pad was forced under the PSU to help keep that 3 - 4mm gap, a secondary benefit of doing this is the PSU sag is eliminated:
Thats all the photos I have for now, I will follow this up with more photos and detailed temperature results.
MSI's BIOS handles fan control very well, I was able to set both the CPU and System fans to run at less than 500 RPM when idle, which was practically silent. This is the first motherboard I've used where the fans keep turning when set below 30% power, in fact I was able to get the Prolimatech fan down to 350rpm at around 20% power!
So far it looks promising from the limited testing carried out, CPU temps are a little higher than I was hoping for, but it runs really quiet so I'm happy. I like running low fan RPMs so this isn't surprising!
Running
Prime95 across 8 threads resulted in a max core temp of 80C after about an hour of testing, the system was fairly quiet, the most audible part of the system was the Prolimatech 140mm system fan.
Running
Unigine Valley the system ran quieter than running Prime95, with the GPU being the only audible component in the system, running at around 77C with a fan speed of 1530 RPM. Unigine Valley was using about 40% CPU, the CPU temps during this test settled around 58C with system and CPU fan speeds of roughly 650 RPM each.
I want to test out some actual games and do some more detailed noise/temp tests, I'll report back with more photos.
