What is a good water cooler for the 3930k or 2600k?

Is what I'd buy, It comes to roughly $346 which is slighlty more than the swiftech kit, however my setup would perform better due to the thicker rad, excellent fans and better performing block, It'll also look alot nicer  

Anyway its just an idea, if your serious about watercooling then you need to do ALOT of research into it and be prepared to take the risk, also maintain the loop...

Air cooling is just alot easier and cheaper and will still keep a 2600K or 3930K @4Ghz cool.

Maybe go air cooling and spend the savings on an SSD or graphics card?

Nah my grandfather doesn't play games so graphics card isn't worth it   How much better would this perform though? Estimation

Perhaps 10-20% better. Watercooling isn't worth it unless your going for heavy overclocks (4.6ghz +) otherwise its more hassle than its worth.

There's no need to go for the complicated water cooling solutions. Just go for a simple one like the Corsair H60. You will reach 4.6GHz easy.

remember this is sb-e. Runs much hotter  

If he doesn't play games then what is he doing with SB-E?

Why does he need a high end system? I guess it depends on the justification...watercooling isn't really a need for most people, so if you wanted to use that cash for SSDs/RAID/large monitor, etc. If he isn't doing anything incredibly demanding or gaming, you can build a very solid system that will perform as well as a SB-E box. Just because you have the cash, doesn't mean you should overspend on hardware that you'll never use or never be able to value the performance of.

He needs something that will last him a very long time, and he plans on running 8-10 hdd and copy files to all of them. He also does audio editing and a good amount of work on his computer.

I'm not trying to tell you what to spend money on...just making sure everyone on your end is happy with the decision.

What kind of budget are you looking at for the water loop and what are you wanting to cool?

I don't know what sort of budget you're looking to spend, but I'm just saying that a $400-600 CPU might be overkill when a good i5/i7-2XXX will most certainly get the job done well.

If you're limited by the budget, I'd suggest switching to the Z68 platform and spending money on some comfortable peripherals (since those are the most noticeable parts of the computer, IMO). Z68 will still be incredibly fast for the next 5 years or so - Core 2 Quads are still in widespread use today.

My Q6600 is running quite well. In fact, I will likely only upgrade GPUs this year and keep that ol' girl a running.

You could always get the H100, I got it for $110 during a deal, I don't think its much more than that normally. My i5-2500k with a H100 is @ 4.2-4.3 GHz and temps are almost always below 60-65C while under load.

Yeah i'd stick with what these guys said, get a decent closed loop water cooler, and pump more cash into SSD's/PCI-E SSD's or something of the like to limit bottle necks due to Slow drives.. most other water cooled systems are way more hassle to setup than anything, and of course if it leaks your screwed  

For the cost of a LCS cooler like the H100, I'd strongly recommend an XSPC EX/RS/RX 240 kit instead.

Otherwise, I'd say find a good air cooler and ensure great case airflow (which you should do anyway).

I bought a Corsair H100 for $89 on boxing day and stuck it on a 2600K at stock GHz.

Temps at idle on low speed setting : 25C

Temps at full load on low speed setting : 46C
( Nero Recode maxing all 8 threads for 30 minutes )

Not suggesting... just what I have.

Theres not really much point in SB-E assuming grandad isnt going to do 12 things at a time. Just slap an H100 on a 2600k and clock the s**t out of it. :-)

Eh the problem is when my grandfather has his mind set on one thing, for an example this. He will buy it no matter what, so i can't really convince him to get an i7-2600k...Total budget for the sb-e system is $2000, so I guess 200-400 for a water cooling kit?

Throw him a swiftech 220 or if he wants it to feel real the Rx or EX240 so he can poke the drivebay res with the pipestem now and again,
just educate him on things like don't let it leak or freeze

I just few days ago changed my CPU water block form OCZ Hydroflow to Swiftech Apogee HD. The new water block is really good. You have the option to use the additional (2) intake & output ports to cool your RAM besides the CPU. It's something you don't have the option with the top Koolance CPU water block.

Swiftech Apogee HD

Theres no real point to including the ram
too much restriction to flow and most decent ram these days runs cool with lower voltages and heatspreaders,
but that block does look hardcore hehe

Remember that when you parallel split your loop, your flow rates halve and your pressure drops by at least as much. While it's a novel idea if you wanted to run essentially dual shared loops with 2 pumps but 'sharing' the same water and reservoir, I'm not a fan of using it as a parallel splitter on a single pump loop.
