Gigabyte EX58-UD5 Mosfet/NB/SB Blocks

[systemviper]

Doesn't the Koolance Mosfit blocks fit any board, their design is very flexible and look like they should work with this board.\

Plus they have bottom plates that make them adjust to even more sizes.

The MVR-100 is a universal water block for motherboard MOSFET-based voltage regulator circuits. Koolance offers various swappable cold plates for the MVR-100 to fit a wide variety of motherboard brands and models. Materials include copper with anti-corrosive nickel plating. G 1/4 nozzle threading.

The MVR-40 is a universal water block for motherboard MOSFET-based voltage regulator circuits. Koolance offers various swappable cold plates for the MVR-40 to fit a wide variety of motherboard brands and models. Materials include copper with anti-corrosive nickel plating. G 1/4 nozzle threading.

To determine which Koolance heat transfer plate is required for your motherboard, simply measure the length and width of the original thermal interface material for that area. Then, if available, select a heat transfer plate that roughly matches the length and width (to within about 2mm, or 1/16"). The heat transfer plate is screwed directly into the MVR-40, and both are mounted to the motherboard via swinging arms.

NOTE: If Koolance does not have the correct size of heat transfer plate for your motherboard, please let us know your required size. We will try to make one available if we receive sufficient demand. As a special note for ASUS owners, the MVR-40 with MVR-PLT755 is the combination which replaces the earlier Koolance VR-AS40 VReg cooling block.

systemviper: Those blocks do look suitable thanks for the link!

Again, as soon as my... rather frustratingly delayed anti-static stuff comes (yes I'm paranoid) I will take the measurements and post back all the blocks I can find compatible with any bit of the board. Of course a block that is perfectly sized for the motherboard would be preferable or even better a single block that covers both sets of MOSFETS (very specialist) would be ideal. I'm very interested in "full cover" blocks that cool both sets of MOSFETS or both the Northbridge and Southbridge but I'll take what I can get .

Lukee: I’m really not the one to ask on what is necessary and sufficient when it comes to water-cooling. I’m sure the Gigabyte manual explains what you should and shouldn’t do to cool the board with the stock cooler and I imagine that the board will perform at least as well as the stock EX58-UD5 if you follow the guide lines. Perhaps you were using it as a figure of speech but having all four fans blowing INTO the case would likely be less efficient than having some exhaust fans too.

In other news Bei Fei has responded to my PM.

Bei Fei -

The only way I would consider making a block would be if I had the board. There are to many unknowns to make test blocks and send them to people without testing them myself to make sure they don't make unexpected contact with components that will cause motherboard failure.

If you can find me a source for a loaner board I will make a kick ass set of blocks it.

Is there anybody who lives closer to Bei Fei interested enough in these blocks to loan?

Thank you again for responding Bei Fei and thanks for the info about Koolance systemviper.

Hehe, I have exhaust fans at the top and back

I'll let you guys know how it works out after the weekend. I should have all my parts in by then.

Actually, now that I think about it, I have another question.

I was going to replace my mcr220 with an mcr320 since the upgrade to i7. would it be better to run both rads in the same loop? Would that help with cooling? I mean, I'm not going to be doing anything else with the mcr220 so if it will help having 2 rads, then I'd be up for doing that.

CedricFP: I don't have any measurements YET but this is one of the first blocks I will be checking for compatibility. Nevertheless a full cover block for the NB or indeed a block for the SB and blocks for the MOSFETS are still required.

I see. Well if the MCW30 fits, you could always aircool the SB as a possibility. But I too am interested in Mofset blocks.

[Bob101]

Luke: Have you tried Martin's radiator estimator (Links: MCR320, MCR220) and his flow-rate estimator (Link)? How well your loop will work depends mildly on the flow rate and strongly on the amount of heat dissipated by the radiators. More radiators = more heat dissipated (for a given flow rate) + slower flow rate (for a given pump). The key is balancing these two, if your pump is powerful enough to still give a "good" flow rate with both radiators and if the heat load is high enough this will likely give better temperatures, if the radiators overload your pump and kill the flow rate then expect worse temperatures. If your heat load is low then adding another radiator will likely make no measureable difference at all. In the end the best way to establish which works best is to try both . Some guys with more experience might be able to advise you far better than I could on this... maybe open up a thread asking for help designing your loop? I did for my new P.C and it helped immensely.

CedricFP: I'm one of those "principle" guys who just irrationally wants to water cool every tiny bit of his pc however impossible this task is . I don't know how rare that is here.

[Lukee]

when you are putting in the watts in the MCR320 spreadsheet. Is it just the watts of the CPU or do you have to factor in some heat from the vid cards since they are also in the case even though they won't be cooled.

[Bob101]

My anti-static equipment finally arrived and I have now removed the stock cooling from the board.

I’ve taken some nice photographs of what we have to work with. To be honest I don't see us finding any generic blocks that cool the tiny group of MOSFETs I've called "MOSFET 3" or the Gigabyte SATA 2 chip.

I could not find an accurate way of measuring the block spacing so I have not included those measurements though I have included photographs of these spacings.

[systemviper]

man they look so much like the Asus design, it's a shame they couldn't keep the spacing equal

[Bob101]

I have now posted up above the measurements I was able to take.

I'm not sure if the spacing is anything like any of the asus mosfets, I will look at the asus spacing tomorrow, it's getting pretty late and I have a new soundcard I'm wanting to try out.

Are there any solutions for cooling anything like the "MOSFET 3" area above? I don't recall seeing any previous mosfet blocks that could watercool anything like that, though I can't say I've been looking. Honestly, it seems like it's going to be pretty damn hard to cool that area in particular with water.

[Apollo4g]

I just bought the board. Thanks for the great measurements.

I plan to use some enzotech MOSFET coolers on mine. Ill have to modify them a little bit though.
