[QUOTE=kladner;343263]I guess cooler advertising has not caught up with the latest. However, from Wikipedia:



However, footnote #4 yields this info-

[url]http://www.pcper.com/news/General-Tech/Noctua-Offers-Free-LGA-1150-Haswell-Mounting-Kit-Upgrade-Older-Heatsinks[/url]

This rather implies some sort of difference between LGA 1150 and its predecessors.

Here is the "Contact Us" link to the Cooler Master online store-

However, the one time I wrote to them they took forever to respond.[/QUOTE]

Thank you! :bow:

The contact line was actually offline, so I sent them a message.

Sadly, their products' download directory was empty, the Air Cooling download page was empty, no information available.

Checking the forum... Empty (the page was the copy of their home).

Stunning, deafening silence in their site...

Anyway, from a different forum I got this:

[code]
Because the LGA 1150 socket keeps the same mounting hole spacing as the current
LGA 1156 and LGA 1155 sockets, many newer Noctua cooler will not need the
mounting kit upgrade, and can simply be installed into the Haswell machine as is.
In other words, if the heatsink worked with your Lynnfield, Sandy Bridge, or
Ivy Bridge-based system, it will work in a Haswell system as well. According
to Noctua, the following coolers are already compatible with Haswell
[/code]

Thanks Klander.

Dear Mr./Ms,

Thank you for your inquiry.
Yes the Hyper 212 EVO is compatible with the Haswell CPU.
The Haswell CPU has socket 1150 and all 1155 CPU coolers
are compatible with socket 1150 because these have
the same dimensions.

Kind regards,

Michiel Bos

Excellent! :tu:

Today I tried to set the system up again.

Unmounted the GPUs, the motherboard, got rid of all the accumulated dust, polished the back of the GPUs with a cotton swab (well, ok, at least 10 of them), mounted the Coolermaster Hyper 212 Evo, and applied the thermal compound, remounted the whole wworkstation and, hey, everything is working fine and at a double speed!

Thanks to everyone who helped me with messages and hints! :bow:
