I plan on buying this mini pc with the 4800h & the am4 socket is 90mm x 54mm, so do you think it would fit? If not, what would? I have no idea of the dimensions of the heatsink mounting holes yet but I messaged the seller asking.

This is the eGlobal AMD Ryzen 7 4800H Mini PC.

Socket dimensions are standardized based on their platform. AM4 mounting locations are equal across all AM4 motherboards. Wraith Spire was designed to be used exclusively with AM4.

Thanks. The 4800h is using the FP6, but this board has a proprietary mounting dimension for the heatsink. I think its 80mm x 80mm... Know of any sockets that may fit that or anything close?

I found this... It's the LGA 2011 & it's 80mm x 80mm mounting dimensions...

It's unlikely that FP6 mounting holes will match AM4. I can't find mounting locations for heat sinks with FP6, likely because it's a mobile platform. However, the package dimensions don't match.

AM4 package = 40mm x 40mm

FP6 package = 25mm x 35mm

Edit: That you should help identify compatibility is unlikely. To reiterate, I can't confirm your question but it's highly unlikely AM4 mounting = FP6 mounting. As per the logic of my first response.

Thanks. I messaged the seller of the mini pc because I think its a proprietary mounting heatsink design. I'm thinking its 80mm x 80mm though would be my best guess. Which would allow a LGA 1366 heatsink to fit because the mounting dimensions of LGA 1366 is 80mm x 80mm. What do you of this 1U heatsink? What is the height of 1U heatsinks by the way?

This is a Dynatron 1U LGA 1366 heatsink.

I'd advise waiting for the dimensions to be confirmed. It doesn't appear 80mm x 80mm. Looking at the photo (which is on a skew / bias) the X dimension looks shorter than the Y dimension.

I'd try finding a cooler that uses a mounting system that works with both LGA155x and LGA1366 mounting holes. The difference between the two is 75mm vs. 80mm mounting holes. There are cooler mounting systems that work on both with the same parts.

Here's an example of a cooler that can be mounted on both LGA155x and LGA1366, the "Scythe Shuriken 2":


I'm sure Slaughtahouse is wrong about the X and Y dimensions being different on the rectangle for the holes. The photo is taken from an angle and not taken straight down, that's why things appear not-square when measuring the pixel distances. You can see that the mounting holes are a square in reality because of the fan (the fan is square).

I tried to factor that into my analysis of the photo but its too difficult to tell. You could be very well correct and I like your strategy (LGA155x / 1366).

@deepor Thanks yeah I agree about the angle at which the picture was taken, wasn't square. Although I do believe its 80mm x 80mm or close to. I was thinking about going 1U heatsink since my chassis is 47mm thick, the Scythe heatsink/fan is 58mm tall. So 11mm too tall, to close the side cover.

I'm still waiting on a reply from the seller so idk when they will reply, they are in China. I believe 1U is about 28mm tall, so that gives me 19mm to work with. Maybe I could use a 15mm thick 80mm Noctua fan? Leaving 4mm of breathing room between the side cover & the fan?

Do you think a 1U pure copper heatsink from say Dynatron of the LGA 1366 variant would be sufficient to cool a 54 watt or higher AMD Ryzen 7 4800H?

Dynatron G129 CPU Cooler - Newegg.com

Overall Dimension: 90.0 x 88.0 x 23.5 mm
Weight: 1.025 lb (So its pretty heavy, its said to hold 95 watts too)

Thanks

I believe FP5 and FP6 use the same mounting.

So they finally measured the fan at least on the eGlobal AMD Ryzen 7 4800H mini PC & it's 62mm x 62mm.

So I'm guessing it's a 60mm fan, unless it's a proprietary 62mm fan... The heatsink looks to be identical size. So I have to find another socket which is 62mm x 62mm.

Any suggestions?

UPDATE The lady at eGlobal said the heatsink is 62mm x 62mm, likely the fan is 60mm x some unknown height.

I found something mentioning 61mm x 61mm here in the following thread in post #32, the size looks like it's used on some graphics cards:


Finding a cooler could be really annoying and you probably can't find something strong with heat-pipes.

Thank you so much for your help! Does this look good to you?

I found the StarTech FAN3701U, which is a Socket 370 heatsink. It's a shot in the dark if the holes line up but its very close dimensions wise. It also weighs about 0.5 lbs, so it should be able to handle a little heat. I plan on using a Delta 60mm PWM fan as well with 40-50 CFM of airflow instead of the weak fan that it comes with. I will also obviously remove the mounting bracket.

The dimensions are, so I think just maybe I can get it to line up & fit, plus it's pure copper so thermal performance should exceed the stock all aluminum heatsink.

64 x 63 x 10mm

Thank you for all your help. I think I'll measure the heatsink myself when I get it. However the heatsink looks as wide as the sodimm slot. A sodimm is 67.6mm & eGlobal said from the center of screw to screw was 62mm. So the outline of the heatsink is about 67.6mm. I still think the socket 370 1U Startech heatsink I found would fit best 64 x 63 x 10mm.

I don't know that I'd trust a socket 370 cooler to protect a 4800h. The biggest socket 370 CPU was the Pentium 3 1400 - a single core chip with a peak TDP of around 32W. The 4800h spec sheet shows a 35-54W TDP. It would probably boot, but I bet it's going to throttle hard any time it does any kind of work. If the mini PC has an included cooler, even if it's bare bones, it's probably going to be better than the one you found.

Thanks. I'll test both heatsinks. The stock heatsink @ 45 watts hits 91C which is way too hot for me. Plus the StarTech FAN3701U is 0.5 lbs which is quite heavy, says it can handle some heat.

I plan on replacing the fan with this one or this one.

So I'm thinking the 2nd one is better because it's a little quieter by 10dB but also 10CFM less airflow. So I'll probably test both fans on the stock heatsink & with the all copper heatsink & report my findings back here in case someone else buys the eGlobal AMD Ryzen 7 4800H mini PC. They also have a 4600H model & many others as well. The 4600H is $478 & the 4800H is $550. I'm going for the 4800H model.

I would think twice about putting a delta fan on anything you're going to be nearby lol. They are known for their incredible airflow, and well, incredible noise :D

I guess the best you can do is wait until you the mini pc arrives, measure the screw dimensions, and plop on something that fits and can eat heat well(at a relatively low fan speed). Wish you all the best and update the thread when you receive the mini pc as it peaked my curiosity. I have this little guy: 【攀升迁跃者M】攀升 迁跃者M 迷你办公游戏台式电脑主机(AMD锐龙7nm 6核R5-4650G 16G 512GSSD WiFi 蓝牙 3年上门)全铝版【行情 报价 价格 评测】-京东 as my Hifi network streamer and love it.

When I'm home from work I'll open it up and measure the socket screw dimensions, it should be the same as yours(just a very different cooling design).

Thanks man. That little 4650g looks nice for a compact mini pc. Whats the thermals lookin like on it @ idle & load?

As for the Delta fan yeah I'm more about performance than I am about noise. I'll be fine with it being noisy as long as it loads out much cooler than 91* Celsius. 91* Celsius is just too hot for me.

I'll update the thread once it arrives, its coming from China by FedEx so it may be a little while to arrive to the USA.
