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

[Clump]

OK
Q6600 at 400*9 for 3.6 GHZ.
Vcore is 1.46 (per probe, don't remember what BIOS setting is LOL). It's prime stable for 4 hours +.

All other voltage settings on auto.
Per probe:
NB - 1.62V
SB - 1.07V
SB2 - 1.52V

CPU block is a D-Tek Fuzion. Rad is MCR220. Running rad fans at 80% using Qfan in BIOS.

Idle:
CPU - 42C (Lowest core is 39, high 44)
NB - 39C
SB - 40C

Prime 95 (large FFT) loaded for about 1 hour:
CPU - 60C (Lowest 57, high 62)
NB - 46C
SB - 46C

I have not run with the NB air cooledd, so can't compare. Seeing the 10 degree improvement from remounting looks like it might worthwhile though!

Too many posts with stock settings. In my opinion they are useless. Also, what do you mean by load.
If we want good readings and reproductible results, some more rigour methodology is needed.

- NB voltage
- A quad core or dual core (quads will produce so much more heat)
- What OC setting people are running and CPU/SB vcore: it will increase mosfets and SB temperatures, and through the heatpipes, the NB will be less cool
In my opinion, you should OC your quadcore at 1.5vcore and your NB to 1.6-1.7v and see how it does. Anything stock or a C2D won't need watercooling the NB with the massive heatsinks. As soon as you extreme OC: that passive stuff will be limiting the NB. I'm also daring about the mosfets, for sure passive cooling won't be enough. That's my opinion, I don't have an X38, but hey, it is hotter than a P35 that already needed active cooling on high quad overclocks

Thanks for shaking the stick at me. Chart data level has been raised.
Good idea!

Thanks for the post Clump!
Outstanding data to mull over...

Prime 95 (large FFT) loaded for about 1 hour:
CPU - 60C (Lowest 57, high 62)
NB - 46C
SB - 46C

So after running Prime 59 for a full hour, using the stock ROG cooler, you managed to get your NB temp up to 46C.

That is a decent temp for full load correct, or is 46C on the warning track for NB temps at full load? Does INTEL have an official stand?

So far:
ROG Member ----- NB volts -- NB Loaded --------------- CPU ------------------
Renegade5399 ---- 1.65v ------ 34°C ------------ Intel Core2Duo E6850 G0 @ 4ghz
bill d ------------- 1.30v ------ 34°C ---------------------------- Q6600 Stock
ragge86 ---------- 1.65v ------ 36°C ---------------------------- Q6600 @ 3.8ghz
j0nnyr0773n ------ 1.54v ------ 44°C ---------------------------- Q6600 GO
Clump ------------ 1.62v ------ 46C (After 1HR or Prime 95) ------ Q6600 @ 3.6ghz
raju -------------- 1.65v ------ 49°C (Prime95 Torture Temp) ----- ??????
Note: After Raju remounted, max temp went down to 39°C

I realize this is not a real scientific test with all the possible variables taken into consideration involved in water cooling, but the goal is to just get a ball park figure of what temps the average consumer might expect to achieve running the stock ROG cooling. We then need to determine at what point does the NB actually start to loose performance due to excess heat. The root question is: Is the ROG cooling good enouigh to not impede performance in any way, and if not, at what NB voltage or temp do we start to take the performance hit?

OK

@Talonman: if I read well, he didn't use the stock cooler (passive), he watercooled his NB and if I read well he reseated it with a 10°C temp gain.

The X38 runs hotter than a P35 and some say hotter than a P965. I doubt any passive cooling will do it at above 1.6v on high FSB and a quad core. 9x400 MHz can be achieved on many P965 chips (except mine ) at 1.45v for the NB.

ASUS and all other brands had their stock thermal compound always low low grade.

Personally, and if I see the Maximus topic, things are presenting bad: Only 2-3 people got a 3.7-3.8 GHz on their Q6600 G0, and none have posted a Prime95 small FFT and Large FFT screen.

What I advice anyone to do: as Raju said: reseat the stock cooling heatsinks with some AS5 or MX-1.

I'm really interested in your great topic though, would be very interesting if people post detailed data like clump did, with all needed info

Personally, once I order my Maximus (yep, I'm tempted as soon as I see some Q6600 G0 stable at 3.8-3.9 GHz above 1.5vcore to verify how the mosfets and X38 manage it at these heavy loads), I'll remove the stock heatsinks, sit my two HR-09U on the mosfets (with 2 x 60mm silent fans), I'll put my HR-05 IFX on the SB, and I'll cut the heatpies from the NB block to watercool it using the stock fusion blockk

Yep, I'm mad to demolish that beauty circuit, but I'm sure, passive cooling will never manage extreme OC.

Hope to see more data soon on the limits of the stock cooling on this Maximus

Again, great topic

[bill_d]

seen where 6 or 8 people pulled nb off board or apart trying to reseat if new umpowered up it works most of the
time but i know my luck i'd get a hole where nb was and i don't need a 280.00 square frisbee to give to the dog

[hornet]

You put 13 pictures and 1 video of your PC in my thread, and didn't report any temps?

Edit it, just leave 1 picture for referance where we can see the entire loop, and report your stats n temps.

I would say keep the last shot. I like it best myself.

That would be appreachiated. She is a beauty for sure.

This post will be edited to ... Thanks for the post hornet!!

And your data will be added to the chart, and recorded for all time.

My excuses.

It was without any intention.

It is rectified.

Malik, your new gear looks great!! Very cool.

Are those mosfet backplates being sold? If so, where and how could I pick up a pair?

Any information pointing me in the right direction would be appreciated!!

TIA

If you are on LPDC it is alright, if you are on HPDC, the barbs at a 90°C angle are a real mess
Sorry, this is out of subject anyway

Never force the heatsink to remove it. Unlock the plastic pins or any screws, and apply a hair dryer for 20sec on the heatsink you want to unsolder. It should come without any effort. If you still have resistance, don't twist or use any kind of lever tricks as advertised on some forums, just give it some more hot air with the dryer. When the heatsink is well hot to the touch, it will come without effort

Just to clarify:
I'm using the stock block watercooled. I have not reseated the block, but am tempted by the possibility of a 10C drop.

[Talonman]

Thanks for the clarification, chart stands as is!

If any would like to include 1 picture of their system for reference, when reporting their temps, consider it officially incoraged !!

You will notice I haven't been recording the idle temps. Only reason being is that I am already giving the stock ROG NB block on water, full credit for being able to keep a system happy at idle, no matter what processor.

But please, do include any and all stats and temps you would like in your post.

I really am after the failing point, and exactly what, if any, the sexy new block would give us ROG members in real world performance.

I think the voltage, NB temps, processor and it's operating frequency, should hopefully show us a pattern?

I only seek the truth on the performance of the stock Maximus SE water cooled block, and if it's hurting our OC'ing ability.

[Renegade5399]

Hornet, I <3 your setup. Nice work there sir, most excellent indeed!
