I tried a Mac for video editing...

650W would be massive overkill since you aren't using a high end GPU. (Though you'll be all set for a future CUDA upgrade or a RAID array...) Water cooling would be massive overkill unless you're planning to overclock a lot. A $30 Cooler Master heatsink will handle even a 6 core i7 just fine.

Well, I'd probably be silly not to try and overclock it at least a little with the K CPU, chipset support, and water cooler (which hardly cost much extra).
Overkill is what I want. That hopefully means lower temps, and hence lower fan noise all round.

If overkill is what you want dave, what i threw in with the videocard is the definition of overkill

Congratulations on your buy! Hope you can figure out a way to make a live shoot or whatever.

Just fiddle with it. My BIOS can do an automatic overclock ("Performance" setting). It tries some stuff and reboots a couple of times. Result: 15% OC (4.2GHz) on a i5 3570K. However, I didn't like the settings very much. CPU base clock 103MHz (), voltages were raised by 0.075V (=a ton of heat), which didn't seem necessary for me.

I reverted to stock and upped the multipliers a bit myself. 10% increase is pretty easy achieved I think. I went for core multipliers of 40 (4-core load, stock 36) to 42 (1-core load, stock 39). Found out the limits were about 43 (4-core) to 45 (1-core). Best is to let it 'burn in' for a couple of hours to a day, to see if it's completely stable.

I dunno what stock fans the Corsair cooler delivers on their water sets, I believe they have special "Static pressure optimized" series of fans that cool better on radiators and heatsinks. Atleast a radiator comes with big 120mm fans

I really liked your blog post too, the emphasis on 'cheap' is nice. I too aim to spend about 600-700 euro on an upgrade set (motherboard, memory, CPU and dedicated GPU).

Yes, I would want to get every last MHz out of it, I might just up by 10% and if it works, good enough.

Yes, won't know until I open the box.
Someone mentioned the pump is load, I hope that's not the case. The box says 6dB quieter than a stock Intel fan. But perhaps any CPU heatsink is?
Any better suggestions, I guess I can still change it.
But this test report says it's pretty quiet, blends into the room background noise

And that would not include my sound dampened case either I guess.

[EEVblog]

The Coolermaster Hyper 212 claims 36dbA noise level. About 4dB better than the Corsair H55

And this list is very comprehensive!:

Looks like I should replace the Corsair H55 with this one.

Dave,
ont he subject of overclock, modern 3rd serie K cpus are VERY easy to overclock leaving practically everything in "auto" because they are overclocked using TURBO bins, not base multiplier, so you get the best of both world, ultra low power idle and super speed when needed)
a 3770K with water can get to 4.6GHz practically stock(i'm running a 3570K with water at 4.6).

now, depending on the motherboard there's a  very cool "trick" setting that essentially enables 4-core full turbo(as you know, intel turbo multis depend on how many cores are active, officially intel has 4/2/2/1 usually that means with 1 core active you get 400Mhz more), that trick setting essentially forces 4/4/4/4 (or whatever your top multi gets set, might be 8, 10, 20, etc) which means you get FULL speed for processor intensive tasks like video encoding

the hyper 212 is THE wonder boy of coolers, it's cheap and works a treat, but you can't beat the thermal inertia of a big water cooler (granted a 2x120mm radiator one).

and a short timelapsed build video with tests would make for a nice altzone vid without running too long.

i'll post screencaps of my bios settings later(i have a msi mainboard but settings are named very similar)

[dimlow]

After my last feck up with the timings on the 3930k you more than welcome to ignore this, but i have had both the H55 and the H80 corsair coolers. Whilst they are ok for a standard system, once you start to overclock and generate heat they get VERY noisy. This was the main reason for my taking the customs water cooling route.

[peter.mitchell]

I wouldn't do anything drastic with the cooling until you have the computer put together and see how it is.

Pretty much the first tweak I did on my 3930k was to turn all the Turbo multiplier limits to 38 (3.8GHz) and adjust the fan settings to be more aggressive. (And I highly recommend the Cooler Master 212, it's cheap and works great even on a 6 core.)

Really, the whole reason why Turbo Boost exists is because once the consumers stopped caring about GHz, Intel realized that they could make a chip that can do 3.8GHz, but then they could downmark it to 3.2GHz (which, of course, the consumers didn't care about anymore) and allow automatic "overclocking" back to the 3.8GHz rating. For basically no real work, there's a new marketing feature!

I wish it could handle my 6 core; almost nothing apart from extreme solutions can handle my i7-990x

One of the issues many people run into with video editing is editing applications that stutter, crash, hang, etc.  The programs are not usually at fault and neither is the hardware of the pc. Something to understand about video is that codecs that are used for playback are not designed for editing, when you attempt to edit a video that is using one of those codecs it is very hard for the editing software to work correctly because codecs do funny things with the video to make it smaller.

I do video editing as a hobby and after months of playing around someone online gave me the info above and told me how to solve the problem, change codecs to one designed for editing. It can be problematic if your camera already produces compressed video because that means another conversion, but if you have raw video already, or if you don't mind the conversion, try the codec below. Warning it creates really large files for editing but smaller than just converting to sequential images.

Once I used that codec I never had trouble with editing programs again.

In 4 years of doing this using the H.264 (and now AVCHD variant), I have had absolutely no issues with editing any of the files directly.
When I first started blogging and was editing on a very old machine that was slow, I asked on a specialist video forum, and they all said I was crazy, you CAN'T edit H.264 directly, it's not designed for editing, not even on the highest end machine with $10K software, blah blah.
They were wrong, as I was doing just fine (albeit a bit slowly and stuttery as you said) using $50 ULEAD Video Studio on a crap old hand-me-down Celeron machine I think it was.  And once I upgraded my machine, it was just fine, smooth as silk.
So whilst that may have been true once, it's hasn't been true for at least the last 4 years, possibly 5 years at least.
There is no need to convert your camera files before you edit them.

[grumpydoc]

There is no need to convert your camera files before you edit them.

Probably true but I still do that for a couple of reasons.

My Canon generates 25fps progressive video but presented as a 50fps "interlaced" stream so I undo that. My Panasonic generates 50fps progressive so I filter that down to 25fps progressive  - that way  I can edit them together.

I tend to use "lossless" H.264 as an editing format.

To be fair no temporal or motion based compression scheme is ideal for editing because any "seek to frame N" might be "seek to frame N-m, work forward to frame N" in reality. Adding backwards predicted frames screws it up even further because the frames then become out of order in the stream.

Same with my two Cannons. Never had any issue with it though, although I rarely mix other video.
But yes, there are always niche reasons to do it. Most people don't have to worry about it.

It really depends on the source video , I have edited some video that worked great compressed and others the wouldn't . After having used the conversion process to lagarith I will never go back to editing compressed files, the improvement in speed and  editing just works too good for me.  Try it just one time and see how fluid editing is after conversion , I can select any frame or scroll through the whole thing in a second even on slow machines.

I can do that too, completely fluid and seamlessly, directly on the full HD AVCHD .MTS file from the video camera in Sony Movie Studio. Even while transcoding a HD video in the background that's using close to 100% of all my 8 cores!
You must have a combination of video editor and source file that does not work properly.
And like I've said, I've never had really this problem on a modern machine, with at least 3 different cameras, file formats, and many video editors.

[EEVblog]

It really depends on the source video , I have edited some video that worked great compressed and others the wouldn't.

If you find a combination that works, why not use and stick with that and completely eliminate the conversion process?
I would go insane if I had to convert all my video files before editing, men in white coats would come and take me away...

[EEVblog]

Dave. I'd be interested in the comparison of the stock cooler (both noise and temperature) performance after 20mins running full on against the water cooler solution.. Standard and with varying degrees of OC.
How far can you go before the CPU temp hits the Intel spec?
Is that asking too much?

Probably!
Surely scores of people have already done this?, look at the thermal results from some of those links I posted.
I'd rather be making electronics videos than computers videos.

[Lightages]

For simple editing, like Dave does, intermediate conversion is really not worth it. If you are editing something with lots of fancy transitions and effects and overlays then it can be worth it. There is no sense using up the time and bloating the files just for a blog video.

The UVD acceleration in the OpenCL build of HandBrake looks interesting:
My i7 3770: 75 s (125 MB)
My i7 3770 and Radeon HD 7970 by adding command line option "-U": 40 s (but only 73,5 MB? Well, all the better: faster YouTube upload )
