Does the case standoff lines up with your socket 423 holes? If not, and if the weight of the socket 604 heatsink is similar to consumer heat pipe heatsinks. Just figure out to mount 604 heatsink anyway.

Cheers,

Yes it does, Intel D850GB board and it seems Intel followed their guidelines exactly. I can get standoffs that fit or build a backplate like how and does.

The 694 coolers just seem better built and better designed that the stuff I find for 423 and it seems like they can keep it cooler.

As 423, 603/604 and 771 all share the same hole spacings on the board it's usually possible to swap coolers within certain limits (the later 60x & 771 designs with intergated stand-offs can be a PITA to reuse). Although it makes for a more secure and flex-resistant fixing to screw- mount directly to the motherboard tray or to a separate backplate, it isn't absolutely necessary as some versions of the black retaining bars came with the same simple expanding push-thru pins some Slot 1 retention mechanisms used, like this one fot the MSI 850 Pro2

Learned something new! Thanks!

Try to get a fan controller so you can slow the fan on 604 heatsinks, they were made to spin insanely.

Cheers,

I like the idea of through hole mounting, seems like it would make it more stable and remove any stress on the board, and these 423 boards arnt real common on eBay not like 478 boards

I thought I had a Socket 604/603 cooler in my MSI MS-6385 Socket 423 system so I checked and I have. I must have installed this at least 10 years ago and it has always worked well.

Nice, I wasn't aware of this yet! Learned something new today, cheers 😀
Btw, I always assumed s771 used the same cooling solutions as s775, but mostly because I never bothered to dive into this due to me not having any motherboards using any of these sockets (except s423)

I am not 100% sure about coolers and think they are that same, but know it's pretty easy to install an LGA771 CPU in an LGA775 socket!

I can attest to the fact that a socket 771 CPU in a socket 775 board adapted to work with it (pin swap sticker, plastic guides filed off) works fine with a socket 775 cooler .

I filed notches into the LGA771 CPU as LGA771 CPUs are way cheaper than LGA775 motherboards

I thought of doing that, but filing plastic seemed easier than filing whatever the CPU is made of . Besides, a Xeon E5450 is probably the end of the road for that board (Asus P5K Deluxe Wifi AP) . Even if the socket 771 CPU ever does fail, a socket 775 CPU can still be installed; one just needs to be extra careful about orientation .

As far as socket hole pitch goes, here's a couple of handy guides to refer to

the bigger problems with cross-compatibility come because of either the aforementioned integrated stand-offs or because the relative vertical dimensions between the heatsink base and the IHS surface have changed between sockets, leading to either to too much / to little load or in some cases no contact at all between the two.

Well the sinks I'm eyeballing screw into standard standoffs and are spring loaded
