I've been looking at getting the cheapest watercooling setup for my CPU. I can some good speeds with my new mobo, but my CPU temps are hurting.... I've got the 'low profile' RAM to match up with a 420mm radiator. But I just need the rest. I do WCG crunching 9-10 hours a day while I'm at work. I just want something that will keep my delidded 8700K at a decent temp for 5ghz while I'm at work. I have it at 4.8Ghz, no AVX offset, and 1.29 volts right now, and it runs at 76C average while crunching.

I've been eyeballing a 420mm AIO from Alphacool, but also looking at building my own loop.

What would you guys recommend?

I've been looking at pumps, and their reliability also..... D5 is obviously the best, but seems overkill for a 420mm loop for just my CPU.

I thought about it, but I would like the ability to expand the loop for GPU cooling. Plus i think it will just be fun to build a loop.

Forget I even said 'cheapest,' I'm thinking that's a bad idea when mixed with water cooling.

Anybody know which brands have best warranty support?

It's definitely fun building a loop, and temps are very good too.. maintenance can be a complete PITA though (especially if you end up with some growth or corrosion), there's been a few times where I've wondered to myself why I bother, but I do love the aesthetic and cooling performance so it's worth it to me. Definitely nice for distributed computing stuff like WCG too.. My 6700k rig currently doubles as a HTPC and WCG cruncher, it's nice to be able to run it full load at 4.0ghz 1.24v and never exceed 48c, fans are running almost silent. Even when I push the chip hard I end up in dangerous voltage territory long before I have to worry about thermals. Although that particular loop sucks when the two Kepler GPUs are loaded up, 2x300W + cpu with only 360mm of rad area isn't nearly enough! My main system with 480mm of rad area for a ~160w cpu and 360w gpu is about perfect, more rad area would be nice to be able to run the fans slower though.

Probably worth just getting a D5, you could get a pwm one and drop the speed if you only have your cpu in the loop, but you have the ability to add your GPU (or two) to the loop without having to worry much about flow rate/restriction so I think it's worth the investment, if you buy decent pump/res/rads/fittings you can re-use them in the future

Warranty wise.. Here's my limited experience:

So far I've had EK, XSPC, Swiftech and Aquacomputer stuff.. I haven't needed to contact EK yet, but would like to talk to them about nickel getting corroded off my 1080Ti block in a few small places, the quality seems great for the most part. XSPC is kinda no-frills, does the job, really good price. Never needed to return anything of theirs. Likewise for Swiftech, that was the first watercooling kit I ever had back in the Core 2 duo days and loved it. Aquacomputer make good parts, I did need to contact their support dept about the wrong spacers being included with my two 6GB Titan waterblocks, they resolved the issue quickly and with no fuss. Oh, I did get some Bitfenix hard-tube fittings once that came with o-rings that were too fat, OCUK were happy to replace them but in the end I just found some correctly sized o-rings myself. Tbh I think if there's a genuine issue with any watercooling product you shouldn't really have much of a problem getting it sorted.

The Alphacool 420 is a no brainer if you have the space in your case. The best thing about the Alphacool are the following

1. The waterblock and Rad are both copper.
2. Their quick connecct links allow you to expand the loop to include a GPU.
3. The reservoir is on the CPU block and has a fill hole so that when you lose fluid, due to condensation you can refill it. Based on the side window on the block.
4. For what you get it is inexpensive.
5. There are a myriad of parts that are available to use e.g. any 1/4 inch will fit.

That is too expensive for what the OP wants to do. You are showing a full custom loop that would not be fun for someone with no experience to try.

Just like this.

What is that Asus card in your PC. A sound card?

Maybe when you have some time and our time differences work out we can PM each other and I can show you my rig that has 2 Alphacool 420s in it and give you a detailed list of pros and cons.

Lol @HUSKIE that's a little over the top.
@kapone32 that would be cool. When you got your Eisbaers did they come with the blue or black fans?

Oh wait you're on air...

A 360MM rad intake will keep it cold. For just a CPU loop you dont need a d5, you can easily get away with this:

I have the alphacool pump block and it is a bitch to bleed.

This is my setup for a 7820X @ 4.6ghz:

124837



If you don't bleed it right it will make a rattling noise from the air bubbles. It's also much much much weaker than the $30 pump i posted.

It does look cleaner though, and it is pretty silent (once you get the air out of it).

If you have the space (I like going with smallest possible ATX) then I would build a proper loop with an MCP355 clone - you just can't beat the temps.

So, maybe this is a newb question... but if the radiator was above the block/pump there would be no issues with the air bubbles in the pump, right? Unless there was just a massive amount of air in it?

And about the TC-A pump... it seems like a DDC style pump. Excuse my lack of experience with these things, but, it would not be compatible with the reservoirs that you can stick a DDC to the bottom of, like the EK-XRES, right? I'm thinking of getting something like that (EK-XRES), just for a little more simplicity.

Edit: Missed the last part where you say go with a MCP355 clone. Is that like an upgraded DDC? Probably another newb question, but I'm only really familiar with DDC and D5 right now--everything else seems like maybe generic to me.

Theoretically yeah if you have the rad above the pumprez the air should get stuck in the top of the rad and the pump will run quiet.

Kind of defeats the purpose of a pump rez. I've also seen people have luck mounting it upside down to get rid of the air rattle.

Temperatures are very good with it though, so no complaints there.

I might just get that Alphacool kit, it comes with fans, and is so much cheaper than building a loop. at least the rad and fans can be reused if i wanna throw a bigger pump at it. But then I always forget to factor in the cost of a CPU block.

It's a good plan - you will definitely need another pump if you do a GPU block.

1. I have never seen a WC loop where ARM height had any impact on radiators.

2. I'd skip the AIO and just go custom, Im not familiar with the pump in the kit your speaking to. The only AIOs I can attest to having sufficient pump flow are those from EK and Swiftech.

3. Pump flow depends on system pressure loss. For CPU, I shoot for a usable range of 0.5 to 1.5 gpm. While GPUs usually have far more heat output, CPUs temps are far more sensitive to pump flow than GFX cards. If doing SLI / CF, you can split the flow before the cards, sending half thru each, resulting in reducing pressure loss thru the cards to 28% of a single card.

4. Assuming a 130 watt OC'd CPU and a 300 Watt OC'd GPU being cooled, that's 430 "theoreticial watts"... Abut 30-40 % of that load be handled by the rad a a) the system will never have all components at max load at the same time, and b) a good part of the heat radiated off th blocks, tubing, shrouds, etc.... that leaves 60 - 70% (@ 258 - 300 watts) or so to be handled by the rad.

5. A 45 mm thick custom loop 420 mm Alphacool radiator will handle the following

1000 rpm ~ 199 watts in push / 240 watts in push pull
1250 rpm ~ 245 watts in push / 296 watts in push pull
1400 rpm ~ 272 watts in push / 329 watts in push pull
1800 rpm ~ 359 watts in push / 434 watts in push pull

I'd suggest:

a) Alphacool 420mm / 45 mm thick rad (review below for 360 model)

b) Swiftech MCP-655 PWM

Thanks for the post @John Naylor .

I've gotta list put together from PPCs site. Other than fans, do yo guys see anything missing, or incompatible in the list?
