Custom loop vs Corsair H100 for 3930K cooling - Page 2

post #11 of 36
There is no reason to go custom WC unless you are adding your GPU to the loop. IMO that is the only reason to go for a custom vs a Corsair H*. If you already have good fans a H80 in push/pull will perform just as good as any other setup for anything other than benchmarking. The only think that might put that into question would be a really heavily loaded cpu (server/folding/crunching). A custom loop is flashy/cool looking, but doesn't REALLY offer any benefits to daily CPU processing.

Also, while the closed loop coolers are convenient, I worry about their long term function, as some amount of liquid will evaporate through the tubing over time, reducing the ability of the cooler and unlike a custom loop, it cannot be simply topped off.
A custom system can be designed to specifically suit your exact needs in every way, while the sealed units are by definition a significant compromise in order to be able to work with every modern processor socket. This is a bad thing, IMO, for performance.
Also, for every 10C you can drop the average operating temp of a component, you approximately double its expected lifespan. The components that most benefit from this are GPUs, which can go from 70-90C under load on air to just 40-50C on water. CPUs typically experience a more mild but still very significant drop, perhaps from 75C to 55C during Prime95, the exact amount depends on how much radiator space you have, the flow rate, the quality of the block/pump/rad/rad-fans, and how many total components are being cooled.
Since you already have most of what you need for a CPU loop, I would just sell/return the H100 and buy an XSPC EX420/EX360 or Alphacool NeXXos UT60 420/360 rad, a few fans (Bgears Blasters 140mm for 420 rad or any one of two dozen great 120mm fans for 360 rad), and some tubing and fittings. Run distilled water with a Kill Coil and a few drops of PTNuke PHN and you will have a setup that is orders-of-magnitude better in every way possible than the H100.

What you say makes sense, very logical actually. FYI, I borrowed an Alphacool ST30 and some fittings just to mockup a custom-loop, as I have never built a custom-loop before, it's difficult for me to determine if a bay-res or stand-alone reservoir is best:





I like the 35X pump with its PWM control, but I worry about it heating up in a bay-res.

Maybe it's an over-active imagination, but a custom-loop seems complex; checking the fittings for leaks, leak testing, changing the coolant every 3 to 6 months, etc. I like simplicity, which was why the H100 appealed to me, until I read so many bad posts about it.

What you say is very logical too. Is it really worth the effort building a custom-loop, for a CPU only, when 75% of the time in Window's the CPU will be idle and the custom-loop won't be cooling down the CPU any more than an NH-D14 SE2011 or even an H100? The only time the CPU will ramp up to 100% is likely to be when I'm gaming. You're right in what you say. FYI, I've no intention of water-cooling my GPU, the air cooling is fine, I think.

a custom loop looks way more badass. coolant can get messy at times, but i cant go back.

Yes,
Aln688, you've got the right idea personally too. The custom loop looks alot nicer and yeah. I personally think the front bay res + pump combo looks/works best as you can constantly see what levels you're at and it's easier to watch what's happening. It also looks better in the way that you can see that it's water cooled.

I think If I ever went water, I'd get a different side panel for my case too. The sidefans are pointless and I'd like to see all that sexy inside my case rolleyes.gif

You already have the H100 brother, just hook it up and put your WC stuff on the marketplace. If you EVER have an issue with the H100 corsair will be all over it to try and help you, even if your components are damaged due to it's failure. I think it's an easy choice.

I may lean that way. I'm thinking that a custom loop is over the top for my needs. For a modest OC the H100 seems like it'll do the job, coupled with four NoiseBlocker M12-P fans (which I already have).

That will be interesting to read, please let me know if you post it. You'll do a finer job setting up your custom-loop than I would, that's for definite.

Made a decision, the custom-loop gets my vote (with very short tubing). I cannot install another H100 knowing that other user's replacements had problems and it might have to be pulled out and replaced. The Supremacy block, MCP35X and bay-reservoir are all high quality parts - I just need to add a radiator, tubing and fittings (7/16" ID x 5/8" OD). I hope I don't botch it and leak coolant everywhere, although I've read many guides on this so I should be alright. One part I'm not sure about is the best way to make a T-line for drainage?

Apogee Drive II is a gift from heaven in smaller cases. Easier to fit everything inside and less tubing needed.

ADII + gpu block + 240 at top + 120 at the bottom or back + small reservoir or a t-line. You're done.
Should total at about €350-€400 for silent watercooled 3930k & 590.
Put distilled water in the loop and a bit of PT nuke, you're done. The only maintenance you'll need is a yearly refill of the res/t-line and blowing out the dust from the rad. It's no more maintenance than aircooling or an H100.
Don't start with colored tubing, dyes, special fluids, shiny nickel, ... and all those things if you want to keep it simple and no maintenance.

Sounds good. If a simple coolant refill and radiator dusting is all the maintenance that's needed, that's easy; I thought there was more to it than that. Do you know of any reviews comparing the ADII to other blocks? I currently have an EK Supremacy block and wondered how the ADII compares. Plan is shiny silver compression fittings with Masterkleer 7/16" ID x 5/8" OD clear tubing.
