Ryzen 3000 Air cooler options, convex and undersized plates of popular choices not suited to die....

[MegaPinches]

Cos traditionally the cpu is a little blob of silicon exactly in the centre and every cooler covers the centre just fine. There's no need to have the cooler base covering loads of the IHS if there's nothing under it.

Then AMD decided to put chips all over the place and create drama.

How much it really actually factually matters is all in peoples heads. This is all about differences in temp which will change nothing. But that doesn't stop people or their OCD.

However if making a new model of cpu cooler today (which that isn't) it would be proper design to make the base larger to account for AMDs eccentric chip placement under the IHS.

You make valid points but its not OCD with regards to the convex plates which are designed for centre dies, they are proving to be worse performance from reports on forums ive read (some are). If they are designed to remove heat from the centre then they are no good for Ryzen or atleast far from the best choice and better to look for alternative designs if you haven't bought yet, its good to know this information I think, its early days and everyone is just experimenting. I'm sure if I already had one of them from a previous build I would put up with it but a lot of folk are buying new, may as well look for the best you can.

You are right though, there is probably a degree to how much worse they are, I would like to find out, I bet some are worse than others, The H7 seems particularly bad though from what i've read.

I wouldn't want that sliver of a plate on the Arctic Freezer 34 though either, nor half the folks here I reckon, I don't know exactly I cant find the die picture I had earlier but it doesn't look like it completely covers the corner die, can't be optimal surely?

With the budget there very good coolers
Just noticed one is bgrade, don't get that one it may not have the am4 mount depending on its age

If your spending more buy an AIO coolers. The cooler plate will cover the full IHS

Ah the second one the dual fan model looks decent for the money, but not AM4

Edit: sweet just seen they also sell the mounting kit for 2.99

they sell the AM4 360 mount for 99p it lets you face the cooler in any direction for better air flow

I can't see that one? only the one for 2.99?

 

[MaXxBoulton]

Oooh sorry it's a different brand. I would have a bet it fits too but I cant been 100%

For 95p I would buy one and try haha

My basket at Overclockers UK:

• 1 x Raijintek AMD 90 Degree bracket= £0.95

Total: £0.95 (includes shipping: £0.00)

....layout.

Feel free to add to this list of popular air coolers getting recommnded on the basis of them being good value for other cpu's but actually not that suited to Ryzen 3000 due to the non-central die layout.

Popular recommendations:

Cryorig H7 - from what i'm reading from reddit users this is a poor choice due to its convex plate, people reporting very high temps, the convex plate is designed to draw heat away from the centre but this is less than optimal for these cpu's.

Thermalright Macho - Same again with this

Arctic Freezer 34 esports - have you seen how tiny the base plate is on this, it doesn't cover the cpu at all which is no issue on central die CPU's but with the corner die's this has surely got to be a poor choice, its only half covering that corner die.

Just a head's up for people looking at these since these are best value in thier range but might not be ideal???

Fell free to add to this if I am wrong about this, i'm just going off of what I have read and has certainly put me off the above choices. Even the Mugen 5 is suppose to be convex but it possibly comes down to what degree they are convex

While browsing the AMD reddit I remembered you.

It would appear that actually yes, the heatpipes entirely cover the chips.

Good to know

So all the people saying there cooler contact patch is "too small" are all talking crap...

If the heatsink made direct contact with the dies (delidded) then that might be the case but as there is a heatspreader taking heat away from the dies it's surely the entire heatspreader that needs full contact with the base of the cooler not just a portion of it with bits left with no active cooling?

 

[humbug]

I've marked out the correct orientation and potion of chips in relation to the heat spreader, for anyone who might find it useful.

Edit: @Hotwired illustration is better but mine is still useful to see where the chips are with in relation to the HS https://forums.overclockers.co.uk/t...t-suited-to-die.18861696/page-2#post-32953644

I believe you won't find many coolers covering entire cpu heatspreaders. I don't think any AIOs do.

There's diminishing returns the further you go from the heat source with the most important part directly above the heat source (which is the chips, not the heatspreader).

If you can absorb the heat directly from the spreader that contacts the cores themselves then less heat will spread also.

I have this cooler on my 3600 and it's very good. Extremely quiet and great cooling.

EDIT: It's the Rev B that I have.

 

[Meridiusuk]

So are the be quiet dark rock pro 4 ok for the 3900x cpus. Thanks

I have that combo - highest temp I've seen is 74 degrees. Very quiet too. I have it on standard fan profile and even on full the fans are pretty quiet.

That's good to know as it's sitting on my desk waiting for some more 3900x in stock. Lol you even have the same motherboard I am after. What memory did you use. Any pics. ?

Thanks

Cool,

Got any temps compared to your stock fan?

I went for TeamGroup 8-Pack when it was on offer. Haven't taken any pics.

For reference. Here's my Dark Rock Pro 4 with TeamGroup 8-Pack RAM, Asrock X570 Taichi and a 3700X....tight squeeze!

that is a tight squeeze

i have a dark roock pro 4 on my system also but i have 2 sticks of corsair vengence rgb ram and ive had to move my front fan up a couple of fins the top part of m,y clips is on the top fin and if it wsas much tooler i wouldnt of been able to clip my front fan on

But i really do like the dark rock pro 4 My corsair hydro x waterblock doesnt seem to handle the 3900x well and the dark rock pro 4 matches it on temps Really good cooler and its black its the main reason why i went with the dark rock pro 4 over the noctua d15 whlst i know i can get covers and black mono crome fans for it now it really does make it one expensive air ccoler.
