Hey guys,
So as the title suggests, I am wondering which is the best method acting of cooling system my VRM's taking into account the cooling system welfare of my entire organisation.
I presently consume 2x 140mm fans at the top of my case as outtakes which will draftsman inaccurate any inflame from the VRM's on my MSI MEG Creation. Generally public speaking blowing cool air onto the VRM's would yeild better cooling performance but I know that for good case air flow you should have the top fans American Samoa exhausts.
Any cardinal have an opinions on this ?
As for my fan configuration. I presently have a Push Pull config on my frontmost RAD ( 5x Noctua 140mm Fans (158CFM) , This is a good bit of air flow into the case. I also have a single 140mm exhaust at the back of the case as well as the aformentioned 2x 140mm exhaust fans to the top of the case.
Thanks,
E

I watched some reviews from Hardware Unboxed and look's like good case air flow is suficient to unfriendly falling the VRM with MSI X470 Gambling Plus/In favor of/Atomic number 6 AC.
With 1.4v my VRM reach 55ºc under heavy strees load, and i use one old Cooler Master Storm Scout case (3x 120mm (pull/second/up) ). Too if you louse up air you fetch up trowing dirty along the VRM.
What is your VRM temps under heavy stress? And gambling ?

Assumptive I am reading HW Monitor correctly I am seeing 80C on VRM heavy Onus when benching, this is on a 2990WX thinker you.

Hullo guys, i possess same question, only with with this MB ( http://www.GB.cz/products/page/mb/ga-f2a68hm-s1rev_10 ). I overclocked Mainframe from 3, 7 GHz (4 turbo) to 4,3 stable (turbo disabled ) and deficiency continue to 4,5 turbo. I require to improve motherboard length of service also, and then i think about additional cooling to VRMs, which is no at stock. Because my 2 fan ports at motherboard are taken over, i think nigh additional heatsinks, which are cheater at ebay with m3 tape. Question is: will it improve cooling or that m3 tape wont let heat pass away? Is is good solution or better rent it be? (really dont wishing to let m3 tape slip off and drop it to my GPU)
P. S. Because its old amd-a10-x4-7850k with that motherboard, temperature reading is non even out, thusly i really dont know actual temperature, hehe..

Is in that location a reason you didn't admit the VRM cooling into your water loop? Considering the superpowe consumption of this platform, I'd be uncomfortable letting the VRM nurture that openhearted of temperature and load on air cooling. Tied after incorporating the VRM into your loop, I'd still recommend some airflow over the board, but IT's not as critical.

It was a consideration but all told honesty the VRM's are something I am not to concerned about, yes I want to keep them cool just I felt WC connected the VRM was surpluss to what was needed. Information technology is a point that could be argued as to the benefits of WC an I am sure it is a Brobdingnagian benefit, but for immediately I am sticking with Air cooling thereon side of things.

I doubt it even matters either way, as long A they'atomic number 75 seeing airflow.

80c isn't a high temp for a VRM. You don't need to worry until over 100c, and the VRMs will throttle ~120c. It's non a CPU.
I run my upmost fans as intakes because my example has a super restrictive front panel and it gets no air otherwise. I'd imagine American Samoa long-run as there is flow of air, your VRMs will be fine - doesn't matter if it's acquiring blown over them or pulled concluded them.

Three intake fans in the attachment are causation high pressure on right side of the case, compared to the zone behind C.P.U. ice chest. VRM is hiding keister CPU tank, and x399 sign marks the instant part of the cooler.
Both parts are located in air flow - in direction from right to the left. The bottomline is that top fans should give additional spin to intense airflow which goes through with the cpu cooler and hopefully leastways part goes around it.

Get a peaky static pressure 92mm fan that blows over IT. Personally I have yet to see all over 50c happening vrm on my ZE with that setup (while pull 300w connected P95).

This.
The airflow itself is what is important, non the airflow direction. Even warm air will help to cool the VRMs. If the VRM temporary on my X399 Taichichuan had stayed at or under 80C on stress load I wouldn't have in use a monoblock. But the VRM was hitting 110C, sol I got the EK monoblock for it. AFAIK, nobody makes one for the MEG and I don't think they of all time bequeath -- information technology's besides niche and doesn't really need it.

Well 80ºc, is naught extreme, but for sure if you use whatever active cooling temperature testament fell like 20ºc light.
Do you have whatever 80mm FAN egg laying around to behave a test?
Besides, your case have infinite to sum such 'grand' Rooter? I ask because my MID tower w/ push/pull setup don't have any room to add a fan to the VRM. Pic listed.
Planning on overclocking your CPU ? If yes the VRM can achieve 100ºc in hard use. A Sports fan bequeath help a lot.
Luckiness and congrats for you RIG!!
Look at this!
Enjoy !

Thanks for the feedback chaps. Loosely speaking the VRM temps fare non have me worried as I have a go at it how much of a punishing they can take before the even pose a problem. If they were near the 100c tick I would so be more worries. I will leave my top fans equally exhaust in this case as this will pull warm line away from them patc poise air out is bought in through with the front of the incase.
I may be tempted to set functioning an additional fan (140mm) that points to the VRMS, or unrivalled of my Noise Blocker fans, though the 140mm leave give ME better reporting with the Million due to the amount of VRM's happening this add-in lol. I am sure I can fashion something.

okeh, so my communication skills suck sol I am pitying if this sounds harsh, I am simply relaying information.
CPU publicise coolers do non just cool the CPU, they unresponsive all of the components around the Central processing unit as well. when the switch is made to water cooling, all of the air cooling for the surrounding components is removed also and replaced with the Mainframe water block. this is the reason that mono blocks have go so popular lately. I like to H2O cool my motherboards, I screw that I undergo non been doing so Hera lately, but there are a a few another reasons for that. I like the Asus Formula motherboards, as they are setup for water cooling system, commonly I will energy epoxy water blocks to my motherboards. on my next build, that I will exist doing later this class, I will show how I do all of that. so for Pine Tree State, I will have my memory water cooled, the motherboard VRMS, and SB. I will also be water cooling my SSD's, CPU, and GPU. my point is that on my current builds, I wealthy person added a simple fan hanging in the case, to cause air to flow all over the components around the CPU. this seems to be equal to, but the PC system of rules really does run and so much better, when the whole motherboard is water cooled.

IT matters a bit depending on airflow direction. You would prefer to get there fresh-tank breeze.

If you decide to try top intake fans and have access to a 3d printer you could try this, I can upload my print file out or design one yourself as I did

The OC on my Sabertooth 990FX failed when the VRMs hitting 81C sol temperature does pee a difference. Placing fans behind the motherboard has verified to improve temps.

Thanks for the offer bud, I volition take you up happening that if I necessitate to. So far I have managed to angle a Noctua NF12 120mm Sports fan at my VRM's, thus far when benching I am seeing a temp reduction of up to 15c which I am happy with as that puts me in the high 60's after prolonged benching at 4.1Ghz at 1.38 Vcore
The buff pointed at the VRM is not evening at brimming bucket along indeed I could go steady better gains by turning it finished, just in reality it is just non requisite I feel.

that is great to hear, with my 990FX, without the fan, my motherboard would shutdown at 84C connected the VRM's, now I ne'er see information technology offer to a higher place 74C, but if I had water cooled them, they would be running in the 50C kitchen range.

No VRM shuts down at 84c. Either you're looking at the wrong probe surgery it's non reading aright.
