Msi claims larger heatsinks are better

[NumLock21]

Msi recently made a blog post about how larger heatsink that extends towards the edge of the motherboard gave better cooling performance. They took their b360 motar and compared it with an Asus B360 strix, both in the $100ish price range and the results were, 

The heatsink offers 26% more cooling area, reducing temperatures by up to 12C on a 95W CPU package when compared with the ASUS B360-G Gaming and at the same time, offering 12% better performance due to a much more efficient and calibrated running of the processor.

. They also mentioned

The MSI board offers 7 phases compared to 6 on ASUS, has x4 lanes dedicated to dual M.2 slots compared to just one on the ASUS board (1 M.2 slot @ x2 speeds), and last of all, uses a larger heatsink for VRMs compared to that of ASUS. MSI calls it the extended heatsink and this design is seen on their entire current generation Intel and 

AMD platform motherboards. 

Looking at the design of the Msi heatsink it offers zero air flow to cut through the heatsink, since it's just a giant slab of aluminum. Proper heatsink have slits allowing air to pass through.

Larger area always pulls off more heat. Regarding airflow - you don't 100% need it given the top size is exposed to air going through the case. Additional fins just adds additional cooling.

I feal a "sh$t that manufacturers say EP4" is comming very soon  

[Mr.Meerkat]

So where's my "no shit sherlock" button? Never would have guessed that a larger surface area (regardless of the fins) and thus heat capacity results in lower temps. I thought it would be the other way round...

/s for people who don't understand sarcasm 

[AngryBeaver]

So wait... You are telling me a bigger heatsink also gives your more surface area to make direct contact with air and dissipate more heat! Holy crap!

 

So they toss on a bigger HS and then make it sound like they invented thermal-dynamics. Sigh, they will do anything for marketing these days.

[captain cactus]

Right but it is still flat as a pancake so it won't dissipate any more easily than all the other crap slabs of aluminium slapped onto other boards. 

 

Then comes Gigabyte (of all the manufacturers) and puts an actual "old fashioned" heatsink with actual surface area onto their VRMs on that X470 board of theirs which actually proves the entire point of more surface area is more better, yet people still fall for shit like this (and manufactures still advertise it this way).

 

If anything, this is more of a heat insulator than a heatsink.

[Jurrunio]

so what, neither boards support overclocking. For mosfets, 125C is their Tjmax, so while 75C is worse than 62C, it doesnt matter. to those informed, anyway

sadly, only the most expensive X470 from gigabyte, the Gaming 7, carry such heatsink.

Well d'oh...

Of course it does....

 

And its probably about convection in this case, so it makes sense. Maybe there are other factors like they could also use the I/O Ports as a Heatsink but I doubt they do that...

[schwellmo92]

You guys all ripping on MSI but they obviously have the superior product assuming their statistics are accurate.

that +12% bar looks more like +66.666%, MSI ._. (don't get me started with the temperature bars)

 

also I kinda get that a more proper solution probably costs money, and my gut feel would be okay with a $20 increase for the use of a proper finstack cooler ._. but seriously a block of aluminium doesn't give that kind of confidence

 

also also inb4 GN tears them a new one

It would be awesome if Steven from GN can take a closer look at this.

 

[lewdicrous]

Well technically, the larger the surface area the better, right?

hang on, how to test those heatsinks though o_o

Steve already did a test on the design of the heatsinks. I believe it was an Asus board, where the first revision just had a giant slab of aluminium as an heatsink and it performed poorly. The 2nd revision, Asus cut grooves into the heatsink and the results improved. I can't seem to find it on their site.

[seon123]

The MSI is just going to have a less efficient VRM (4 phase on both MSI and Asus for Vcore), and the heatsinks are both retarded. Because the MSI one is just bigger, I'm assuming they took the temperature from shortly after loading the CPU, so that the Asus one heated up more than the MSI one. 

 

Why can't we just get proper fins? Just get some black painted fins like on Be Quiet's CPU coolers, I'm sure the consumers won't mind...

Yeah , i don't understand why mobo manufacturers such as ASUS , MSI , GB etc put such crappy VRMs and VRM coolers on their AM4 boards . They're confident about AM4 , so why do they skimp on board design ? That wasn't a problem with am3+ , and it isn't a problem for lga1151 , and both of those use the same or more power.

@LinusTech @nicklmg This would be perfect for a "Sh%t Manufacturers say"

I also like how they're comparing their Vcore heatsink with the Asus' SoC heatsink. Confidence.

Something something

[AngryBeaver]

Now they just need to offer a Hybrid motherboard with a 120mm AIO cooling the VRM's lol

because their SOC VRM heatsink is just as much as an art piece.

[Doobeedoo]

Well anything that helpa VRM temps, good. It sucks that if you OC and find out they're frying even on expensive board. 

[ApolloFury]

It still has that problem where the heatsink is a big slab piece of metal instead of fins.

Fixed.

[aezakmi]

Well MSI also says putting a big chunk of metal aka shield or shroud over the VRM section makes the mobo cooler.

They also say a solid heatsink is better than a bonded fin model and so on. Looks good, performs horrible.

[Crunchy Dragon]

In a way, they're not wrong...

 

As long as the larger heatsink is designed properly, it will dissipate heat better.

[DildorTheDecent]

Get rekt MSI. Your comparing heatsinks that are in two different places. Which I assume have two very different design restrictions.

 

Trust MSI to spew utter garbage.
