MCP655 strong enough?

[Hglazm]

So I'm planning out my new WC loop, and it'll be as follows:

EK HF Universal
Bitspower EVGA x58 Mofset
Bitspower EVGA x58 Black Ice NB/SB combo
EK 5770 Full cover
EK 5770 Full cover
EK 5770 Full cover
Swiftech 360 Quiet Power w/ Reservoir
Bitspower 80mm Inline reservoir
Bitspower 80mm Inline reservoir
Swiftech MCP655


Will the pump have enough strength to move water effectively through all that? I've already got the pump, so if I can save a few bucks by not having to buy something with more head pressure that'd be just dandy.

[Edward88]

The pump can handle that. But for such a loop, you should use two pumps.


Your problem is that your rad wont be able to handle all that stuff

Theres no way in hell I'll be able to fit a dual-pump system in the case I'm using, so its one pump only.

Also, I see this a lot. People really over-estimate the amount of thermal output of their components.
A 360 can dissipate almost 700watts of heat (IIRC. It may actually be more).
Meaning, no. I will not get super-ideal temperatures for all parts. But it's got more than enough thermal capacity to cool three mid-range 40nm chips and an i7.

Especially since it'll be pulling off the ground, and not ambient case temps.

[Edward88]

well so if you know so much, dont ask . . .


go with it, i7, nb/sb, mosfet, tri 5770 in only one 320 mcr rad . . . you will be fine

I mean in no way to sound like a :banana::banana::banana::banana: about it. I'm just stating that a 320 has more than adequate cooling, which is why I wasnt asking so much about that as I was flow rates.
People just underestimate the capabilities of their equipment.

Kinda what I was thinking :shrug:

[Hglazm]

Kinda what I was thinking :shrug:See above.
I really don't mean to sound pompous or anything about it, and I'm sorry if I came off that way. But I'm very confident in the single 320, which is why I didnt ask about it. But rather the pump.

If the pump cant move the water then it wont matter if I've got quad 480's.

[Edward88]

The pump can move water through your loop, but i cant tell if it would be enough

You have to pass 1 gpm to be fine

[Serpentarius]

more than enough in my opinion ..... some ppl have your Laing D5 to power a house solar water heater ....

imagine to having that D5 to pump the flow circulating the whole house .... whereas you're using for a less than 10 meter length tube

but for one thing, that single MCR320 wont be enough if you decide to have low temps and an o/c cpu (which most ppl are intrigued to do so)

[Serpentarius]

-double post-

strange, it havent happened before - where's the 30 sec countdown?

Low temps are nice but completely unnecessary to me. If the CPU remains under 55 load I'm happy, and so long as my GPU's are under 70 I'm happy.

Its cool and all to have an i7 at 4.2ghz running at 23c, but its got 0 gain over one running at 55c. Plus, it'll be a hell of a lot quieter than two radiators.

[tool_462]

You'd need a monster loop to keep a 4.2Ghz i7 at 55C loaded :p:

[Hglazm]

You'd need a monster loop to keep a 4.2Ghz i7 at 55C loaded :p:Probably, I was just tossing random numbers. I don't plan on doing a 24/7 clock anywhere near that high :up:

I don't plan on doing a 24/7 clock anywhere near that high :up:

Blasphemy! Any average D0 will do 4.0-4.2 easy with little voltage increase :cool:

[Hglazm]

Also, another question related to the MCP655, I've seen people rotating it so that the intake is facing up and the outtake is facing horizontally.
Is it kosher to do that? I've got a friend who says that'll completely screw up the way it pumps.
If its okay, then is there any way to mount that pump that ISNT okay?


Blasphemy! Any average D0 will do 4.0-4.2 easy with little voltage increase :cool:
Oh, definitely. I'll be OC'ing as high as I can for the sake of overclocking, but because I'm sticking with a single 320 I'll be keeping my clocks low until I find what my temps will be like.
I *may* add in an extra 120 and a 240 along the line, but that depends on how much space I've got left over.

[Serpentarius]

Jesus what



i am serious on the Laing D5 (rebranded as MCP655) being used on housing solar water heaters ... you can check on some contractors standards :up:

:rofl::rofl::ROTF::ROTF:
well, you could also call up your local solar heater contractor, ask for the price of 1 Laing D5 DC pump, maybe you could get a bargain :D (just don't tell you'll be installing it in a computer, they'll ask a whole bunch of questions) :rofl::rofl::ROTF::ROTF:

What? I'm going green :p:

One Laing D5 Vario is fine for that loop. Of course 2 Laing D5's in series would give you twice the head pressure, which will give you a higher flow rate, but will it improve your temps? Probably not. All it will do is make your loop more responsive to changes in heat, however, you may (i repeat MAY) see lower 100% load temps. But as for idle temps, they will probably not be improved by two pumps.

As was said earlier, to improve the performance of that loop, you really should add another rad. And of course the bigger rad you add the better. Your only limitations are your wallet, your case, and your imagination.

[RoadconeTuning]

kinda ballsy to be doing all that on one rad... i've only got the loop thats in my sig and it barely keeps my Q6600 at 70 at 3.6GHz and thats with only mosfet coolers and a fairly wimpy chipset compared to the x58

[Burninator]

I'm surprised no one has asked this... what fans will you be using?

He would say "No fans, swif320 can handle it itself" :ROTF:

I've been pondering the design of the case, and I *should* be able to mount a spare 120. Another 240 is a strong possibility, but that depends on clearance between the top of the case and the mobo (Working with a p182). I'm just being a little stubborn about the single-radiator idea because
A) Provides the cleanest looking loop
B) Is the only way I can for sure do it. I really won't know if I can mount extra rads until I actually get down and dirty with the mod.

Albeit not anymore because my block got completely dinged to hell, but when I first mounted it and ran at 3.8ghz on my Q6600 I got 40c load.
I've got a friend who has an AMD 955 @ 3.8ghz and a 4890 @ 965/1015 and his CPU never goes above 45, with the same radiator.
I'm fairly sure this is because we both have our radiators mounted on the bottom, so they pull the coldest and densest possible air in the room to cool with. Yields much better results in my experience.

Planning on doing a pushl/pull with 6 Cooler Master R4's. Would do Gentle Typhoons but theres no way in hell I'm spending $120 on 6 fans.

[PiLsY]

This should help (http://i169.photobucket.com/albums/u235/matt08071975/ParallelFlowGfx.jpg). Parallel gfx setup will reduce almost all the flow loss introduced through running multiple gfx blocks. I'm using this setup successfully right now. Pay careful attention to flow in flow out positions, you MUST use opposite corners for inlet and outlet to equalise flow perfectly between your blocks. I recommend TFC multi sli connectors as you get 3 different length metal tubes to connect your blocks with. Youll need 4 of these blister packs to connect your three cards. Make sure when fitting them that the connecting tubes are of equal distance into the connectors as it can be quite easy to have them 1/2 in on one side and all but cutting off flow on the other.

Just do the numbers on the heat load you need to dissipate in that loop, I'm sure you end up at least two times your current heat load possibly 3 times, any only a 50% increase the radiator area. The i7 is a seriously hot chip. You are very likely to end up with seriously noisy fans and/or crap temperatures, sure if you WC for looks it will work, but most people want good performance and noise levels.

And I agree we tend to over pump and rad our loops here on XS but you are cutting you radiator short, but the pump will be fine.

Might I suggest some Zalman z3 or Yate Loons instead? Are they going to be horizontal or vertically mounted?

I will do the numbers. MCR320 with 1200 rpm can decipate about 400watt with a 10 degree Delta. Make it a push/pull config and you could reach 480-500 watts. (20% increase with push/pull)

HD5770 TDP = 115, which means in gaming it probably never exceed 80 watts.

So thats 240w.
Leaves you with 260 watt cooling capacity for the i7 + mobo.

Yeah if you do Furmark and Prime95 at the same time you probably can't clock the i7 as high. But for normal purposes (gaming) this setup is:up:

I'm totally with Hglazm here. Most rigs here are completely overkill/unnesessarry. To each their own of course.

1. As far as case/ loop design: I think with some heavy modding, you can get a 360 rad in the top and a 240 rad in the bottom compartment. You might also be able to fit an inverted Black Ice GTS 120 in the rear single exhaust fan spot.

2. Number of rads: IMO a single rad does not look better than 2 rads, and in fact it looks worse, because 2 rads looks like more cooling power than one rad. But then again, everybody has their own opinion about aesthetics.

3. Hooray for the mighty GTS 240! There are many detractors of the Black Ice Stealth series rads, but I am not one of them. I luv 'em.

4. MCR320: it can do the job by itself, but not well. The MCR320 is a very good radiator to be sure, but it is not a "great" radiator. For true greatness you have to look at Thermochill or even Feser for general use, and for specialist use the HW Labs SR1 series are optimized for low speed fans and the GTX series are optimized for high speed fans. Also the XSPC RX rads are in the "great" category, and cost less than the 4 other "great" rads that I mentioned, but IMO give a little less performance than the other four options.

5. Fans: If you really want to do a single MCR320 loop, then I strongly recommend getting the 6 Scythe Gentle Typhoon 1850 rpm fans. Yes they cost a pretty penny, but they are worth it. Look, quality and performance cost money, that is a fact of life. If you bargain shop for everything, you will live a cut-rate life. Sure you'll have a bigger savings account when you die, but was your life really that enjoyable? Now, I don't know your financial situation, and money might be tight for you right now due to the shatty economy, as it is for me, and most of America for that matter, but if you can afford to the get the GT's, I would do it, and I would not simply stand on principle that you refuse to pay more than $X per fan. And besides you can sometimes find the GT's for $14 or $15 on sidewindercomputers.com, so shop around, they are definitely worth the extra money.
