Do You Watercool your Mosfets?

[ballzD33P]

i always thot it was kinda pointless, (like watercooling your SB) but what the hell do i know ....so poll away

[BlueAqua]

It doesn't gain you much but does lower the temperature of them. Depends on what your goals are if you think it's worth it or not.

[Snowfortrick]

hell yes,mi dfi lt p35 is very hot in heavy OC!!!But i think that is a dfi's mobo problem (and i have a quad core),asus generally don't need it

[Sparky]

Since there are no aftermarket sinks for my mosfets I would, but there are no blocks either
So I have a stock sink and a small 40mm fan suspended over it, it seems to work OK.

I water Cool my mosfets But i had to do something since i took my coolstack off to get better cooling on my NB. So i had to do something with the mosfets I could have went with some third party passive air cooled mosfet coolers. They would have worked just fine with some good airflowand cost half the price But I decieded i had too much money in my bank account so i went water on everything even the SB. But i would say it is overkill for sure with Dual Cores, Quads do heat them up a good bit more. Plus if you can lower the temps on a cpu by 10c it is estimated that you double it`s life span. Im sure something simular is true for mosfets. But on the other hand if that makes this board last 10 years insted of 5 years it really doesnt matter because it will be outdated in two to three years ( at least to the point where the new stuff out is twice as fast ) Would make a good server for a long time though. So having said that i dont think it pointless maybe a bit overkill but i do have the peace of mind that my mosfets are not overheating under high overclocks

[shabranigdo]

I don't currently but plan to in my upcoming build. Main reason I see to do it is one less component that needs airflow and gets more heat away from the mb. Also most MB's have integrated mosfet/NB/SB so if going to water cool one you have to ditch the stock cooling.

Same here.

[Xilikon]

I do watercool the mosfets on my Maximus Formula because airflow in the case is so poor that they overheat. Now, all is watercooled excepted the SB.

[TouGe]

I see no need to on my MIIF. I have two 120mm fans blowing down from the top of my TJ-07 w/ TR Mosfet blocks and my PWM temps are @ 31C under full load. I'm only pushing a mild OC of 3.6GHz w/o loadline enabled but I could imagine there are some that are pushing 1.4-1.5V on their quads w/ loaline enabled that might see the benefit of using water blocks.

[RADCOM]

Of course I cool my Mosfets and SB...

If a bock is made, it's going on my MB and getting cooled by water...

What's the point in watercooling, unless you watercool...

Tru Dat! If it gets warm cool it Actually I only have watercooled mosfets for the striker but it looked nice and they did get pretty warm. A cool chip is a happy chip

[T_Flight]

I think the idea here would be what are your temps, what is your OC level, and so forth.

If you plan on pushing insanely high OC's with certain boards you may need them.

There is a point of diminishing returns though. If you start adding more blocks you are gonna slow down flow, and then have to add pumps, and you might even have to add another rad.

On mine, I'm gonna do what's needed. I'm gonna start with a basic tripple rad and CPU/GPU loop, but if I need to add a pump, or a rad, or other blocks I will, but it will depend entirely on the system, the OC, and the way it runs in my case.

From what I've gathered Asus boards run pretty cool on the MOSFET's. Back in the day when i built my last rig people were actually blowing out MOSFET's and caused some of the board manufacturers to come out with revisions to put higher spec'd MOSFET's on the boards after the Prescott's came out. We were killing them...I mean literally blowing them out...blowing burned holes in them.

On my old system I used OCZ RAM sinks and cut them to fit the MOSFET's and the bioard has air blowing over it. It never gets above 43C full load. These neweer boards are very different though.

[Zaskar]

Pointless and usually will prevent you from making a setup that allows for removal of the CPU block without draining atleast 1 of the loops (even if their on their own loop)

Thermalright makes blocks for mos mosfets and even if they don't have one, the generic Enzotech individual mosfet sinks will do the job, the ones on the north side of my 790i don't even get hot.

[IanY]

You shouldn't generalize SBs, but I agree with watercooling mosfets being somewhat less necessary. However, like RRR mentioned, if you are going to watercool the mobo, then you might as well do it completely.

Would you like to try touching the SB of an Asus 680i Striker in operation? It will sear the tip of your finger and blister your skin for days, and then your skin will peel off and it will look ugly for a week. I know because I have tried and have learned my lesson. I have touched kettles of newly boiled water, and the SB is just as bad.

[Lloyd]

i voted yes, but only on 1 out of 5 pc's so far

[MpG]

Yes, but I wouldn't do it again. Not too long ago, it was a legitimate concern, and I smoked my first P35 board because the mosfets above the CPU socket had no heatsink on them, but... it's just not the issue it once was. And even in a seperate loop, it gets in the way of the main loop. And at ~$40 a block + other parts, it's a terrible value even by watercooling standards.

My next build is just going to use a board with a really good stock solution, at which point I'll re-seat everything and put it all in a case with a side-panel fan.

[BreeSpree]

Lol, it is pointless, but I do it anyway. If I can watercool it I will. I mean if its there, why not watercool it.

[Martinm210]

It's more luxury than need, but why not...

I didn't on my DFI, but I did add an old thermalright sink to the mix to help get some of that heat out of the case. I just don't like when you've removed all the air flow from around the CPU socket.


If there was a good block for the DFI readily available, I'd probably buy it though..

[majestik]

I don't think i'll ever watercool my mosfets - and I'd prefer to not watercool the NB either.

CPU + GPU and thats all

[Eddie3dfx]

Yes, Balldeep? I watercool my mosfets

[Pellepel]

Oh yes, y not =p.

Have i got news for you!

aw, no block for the Abit IP35-E
oh well, my little fan works ok

did u have to mod that or dose it just work, and what are your temps like

40 euros is to much for a pwm block IMO if some1 made one for $30 i would get it

[Navanod]

Using 2 Koolance's universal mosfet blocks on my Rampage
Looks good, works well
but tubing routing is a real pain

[SiGfever]

I used two EK Asus3a Acetal blocks on my P5K Premium and then on the P5Q Deluxe before returning it for the Maximus II Formula. With the nice heatpipe system of the MIIF being able to apply a NB waterblock to the heatpipes makes for a nice compromise. I would like to get one Mosfet WB to replace the removable Mosfet block to the left of the CPU though.
