Official Water Cooling Thread of the Stock Maximus SE ROG NB Club:

[E.R]

MIPS-COMPUTER blocks, price: 159 EUR
EK Waterblock answer:

1. EK-NB/SB ASUS 3 - Acetal, price 32.95EUR
2. EK-NB S-MAX Acetal, price 30.95EUR

In all fairness for a complete EK setup you need to add 2x
EK-Mosfet ASUS 3a@ 32.95EUR a piece to be equal to the MIPS-set in wc-blocks. Total of 129.80EUR, but still nicer and my pick anyday.

I just ordered from EK:

(1) EK-NB S-MAX Acetal
- Fittings 1/2" ID

(2) 1/2" ID fitting G1/4

(1) backplate for my CPU.

I am going to cool the NB with an EK block now, and use our stock backplate for the NB.

I think I will just go with a heat sink on the SB.

[Xilikon]

What about mosfets ??

[Talonman]

Heat sink and a fan I think...

Too rich for me right now... I am starting to get into the money reserved for my GPU.

If EK wants to throw a set in my order with backplates for free, I will be glad to beta test them here in America, and post a report!!

The air might be different over here in Ohio, and mabey EK is looking for more data? Heck, I'll take the blemished ones if their EK blocks!!

[Malik]

Hehe, right now my NB temps are down to 21C but it is quite chilly in my office with the windows open. My NB voltage is 1.52v, FSB is 400 x 9 and water cooling the SB is a total waste of money, flow and effort IMO. My SB temp with a passive aluminum sink borrowed from my P5W DH is keeping it at 28C, ive never seen it higher than 35C. I do like how the ROC can come off yet leave the sinks on the mosfets at the top.... IMHO the stock ROC is garbage marketing gimmick.

Could you give some screenshot with this temp to confirm ?

SB is different due to the caps around the SB, NB is differnt as the 4 holers are closer togther.

All the Asus X38 EK blocks are on the way to me as we speak, big thanks to EK for that!

I waiting too for EK blocks

[jonny_ftm]

My computer is always under load running SETI... but I ran the OCCT with the slider to RAM for about 10 mins (damn that makes the comp slow lol), NB temps don't budge off 25C

10mn???
Suere not enough to stress your water cooling loop and your NB
Under OCCT last beta in RAM mode, you'll need about 30mn at leats to get your NB heat maxed out. Depending on the capacity of your waterloop, it can take up to 2h for the water temperature to reach equilibrium

Finally, if your window is open, in winter, the ambiant temperature and the chip temperature in a watercooling system have an exponential relation. That is, a 5°C delta in your ambiant can have a 10-15°C impact on your watercooled chip depending if you're on the cold side or hot side of the exponential curve.

The problem with all the results people give, is that most people don't know exactly what they do.

Using Prime95/CSMT/F@H or OCCT RAM, won't give same load on your NB, so when you say load, should be mentioned what proggy. OCCT last beta in RAM mode is by far the best test

Also, people should test at a 20-25°C ambiant to report values. Testing with an opened window, is really not a reference

Here for you some example to illustrate it

I use here Prime95 small FFT for maximum CPU only stress (NB and RAM stay cool at this test)
Ambiant Air 24°C:



Now, Ambiant Air 18°C



CPU Temp is 51°C for 24°C ambiant air . At 18°C ambiant air (digital thermometre) the CPU is at 35°C. So quiet a 2.5x ratio (delta CPU = 2.5 x delta ambiant air).

This is on the cold side of the exponential curve. In summer, above 25°C, the ration will increase and can reach a 3x to 4x around the 30°C ambiant

I just ordered from EK:

(1) EK-NB S-MAX Acetal
- Fittings 1/2" ID

(2) 1/2" ID fitting G1/4

(1) backplate for my CPU.

My opinion, but the MCW30 is by far one of the best WB for cooling the NB. It is based on the Apogee GT design, so a real winner

[jonny_ftm]

The best would be really a 1-2h OCCT last beta in RAM mode, and give your NB and ambiant air temperature.

[nikhsub1]

pics?

Some pics with the MCW30 plumbed in...

[Jedda]

Love your routing the blue pump wire over your blue RAM sticks. Very cool!

[Talonman]

Sweet... Thanks for the picts.

I guess we will have to see how the EK-NB S-MAX Acetal block stans up against the MCW30.....

My guess is both are winners.

[TheSamurai]

BEFORE = STOCK WITH AIR
Q6600 G0, 3.9 GHz
NBv = 1.54
NB Temp = 48*C

AFTER = RESEATED W/ MX-2 AND WATER ADDED
Q6600 G0, 3.9 GHz
NBv = 1.54
NB Temp = 34*C

before i was using the standard blend of OCCT, after i was using OCCT Beta with RAM setting.

Origional post updated with your data!

Thanks Samurai... Nice drop from the remount!

Looks like our 'Stock' SE cooling, is going to be super SE soon...

The Maximus SE just got a block change and a new name.

ASUS MAXIMUS EXTREME

http://www.newegg.com/Product/Produc...82E16813131235

They are getting more expensive too.

[Talonman]

For people looking to cool their mosfets on air, I'll advice these ones

http://www.thermalright.com/a_page/m...duct_hr_09.htm

They are passive, but you can manage to fit (with some home made stickers) a 60mm silent fan depending on the CPU cooler you have (clearance)

I took your advice Jonny!!
I ordered me 2 up, to see how they work out for me...
So now ...

For cooling my Mosfet's:
(1) Part # cpu-tri-40 - Thermalright HR-09S Mosfet Cooler - Slant Type
(1) Part # cpu-tri-41 - Thermalright HR-09U Mosfet Cooler - Upright Type

For cooling my NB:
(1) EK-NB S-MAX Acetal block

For cooling my SB:
(1) vid-22 Microcool Chipsink Southbridge Passive Heatsink (Might work on the SB, but might be too tall)
-or-
(1) vid-84 Enzotech Forged Copper Northbridge Low-Profile Heatsink (CNB-S1L) (This is the one that takes moding to make fit. Sweet low profile and copper a +)

Not sure which one I will end up using?

For cooling my CPU:
D-TEK FuZion CPU Waterblock

And a WaterKegIII Xtreme!!

I also ordered 5 more feet of Tygon 1/2". I think may need some to install my EK NB block.

I hope I am about done with my cooling stage with the Maximus!!

I guess I will officialy be ousted from the Stock ROG club for sure...

'Operation Removal' will have to be done now!! Gasp!

Yup, thats the sweety that supports DDR3... Wish I had the money, but in time THIS will the the motherboard to get I think.

[Creek Tha Gray]

Just ordered can't wait.

1 x EK-NB S-MAX
- Fittings: 1/2" ID
1 x EK-NB/SB ASUS 3
- Fittings: 1/2" ID
2 x EK-Mosfet ASUS 3a (X38)
- Fittings: 1/2" ID

[TheSamurai]

i think so too. but for now, ddr2 is where it's at. ddr3 is waaaaay to expensive. i have a friend that used to buy the latest and greatest when it came out and he's been screwed so much, money wise, that he's not doing that anymore. actually... he's getting the same gear that i do now hahaha.

[E.R]

For cooling my SB:
(1) vid-22 Microcool Chipsink Southbridge Passive Heatsink (Might work on the SB, but might be too tall)

Why not a HR05 SLI/IFX like i put a order for last weekend?
Will suit nicely with the HR09, only a hard work to find a 80x15mm fan to put on it. Thinking of a nice 80x25mm instead.
I´m not to big of a fan of passive heatsinks.

Great choice, but remember, any passive cooling needs very very good airflow, it is critical, otherwise, they'll end to be unefficient too. Watercooling the mosfets, in my opinion is great, but definetely needs a two loop setup. With only one loop, the restriction will be too much and your CPU cooling will suffer. As, cooling the mosefets is an extreme OC issue, the few degrees the CPU temperature will suffer from restricting the loop could impact your CPU OC performance.

The price/performance ratio of the 2xHR-09 is by far better than watercooling the mosfets even without adding a second loop. In any case, they'll perform better than the crappy stock ASUS cooler (great for medium OC, but not enough for high OC on a quadcore)

As for the SB, the problem is that if you remove the stock NB cooler, you loose your SB stock heatsink, so yes, you need another heatsink. As I suggested before, and said by E.R above, the HR-05 IFX(/SLI) is a supreme option. For only the SB, I'll go passive, no fans needed. It easily fits a 80x25 mm fan too if really needed

I can't advice about the two heatsinks you mentioned, but for suere, they will be less performant than the HR-05 IFX or IFX/SLI versions

[Talonman]

Looks like a good unit.

I didn't want one quite that big of a sink for the SB. I hope the low amount of heat it does create, will be handeled ok by my smaller sink too.

I will be OC'ing a Q6600. I hope my mosfet temp won't hold me back too much!!

But as you said, In any case, they'll perform better than the crappy stock ASUS cooler so I will have to see how it works out for me..

I also was thinking like you that I could overload my 1 loop, and I didn't want my CPU to suffer higher temps. I will let air do some of the work for me...

[jonny_ftm]

Yep, after all it looks too big for only the SB. But, if the price is not a problem (take care to space also) I'd go HR-05 as you can recycle it later for more demanding chips, like a NB in a future setup...

[cuke2u]

Hi, does any of you guys use the add on fan from Asus with your WC? I've mine fitted however if its not needed I'll dispense with it...

If your running the stock Maximus SE on water, ASUS intended for you to use it. I will be switching over to some different heat sinks, and believe it will no longer fit in my system.

I think were probably fine both ways....

[dude_500]

Just got the board and I have a few questions.

I'm running NB at 1.39V at 39* load and my 'MB' is running at 38*. Is MB the ambient? Because that seems extremely high for my case with a 2x120 rad pulling in and 2 80's pulling out. I do have water on the north-bridge.

Also, I can't really justify taking the heatsink off of my new $300 board, so I thought about ways to improve whats there, and thought that every day while it's at load and hot, if I just turn the NB screws a quarter turn, it'll push the trash glue out a little at a time. Could this be possible?

[initialised]

I should be getting mine today. One quick question though: does anyone know what the V2 revisions are?
