Not here yet just a couple hours south of you. So at least I don't think it's an individual thing.
AndrewT,
I'm just happy I found them. I think they were pretty much the only option for heatsinks here that fit the board closely enough. The only other options I was finding was paying crazy money to have one shipped here from EU.
the ups just came, but no boards .
i hope tomorrow ill get them.
I am pretty much in the same boat with "Loafimus",
i am curious if he got them.
is FISCHER ELEKTRONIK SK 92/75 SA a good cooling solution or the Thermal Resistance is too high?

I think they'll come in USPS, not UPS.
Also, in a previous post I had a link to HeatsinkUSA. They have acceptable sizes for the build and can be cut to the height you want so it'll fit in your case of choice. for a 3U case, a 4" cut was perfect. The one you posted should work, but when I looked, it was crazy expensive to ship to the US.
I think you'll want one with a thicker base. I believe I did the 7.280". It looks like the 4.230" one has the same thickness base. I would wait until you get the board so you can measure to be sure.
you're right, i hope ill get them soon.
i act like my kids before christmas , knowing that "santa" will bring them toys.

Yes, that's right! I've double-checked the address at PayPal and it's correct. I hope the boards will arrive this week 🙂

if I remember the BOM correctly length shoud be 150 mm or 200 mm.
I think 75 mm is too small.
The Fischer SK92 150SA has a R(th) of < 1 K/W. Thats better than the Pada from the BOM.

I used the 7.280" - HeatsinkUSA cut to 4". Worked perfectly in a 3U case. I honestly think it may of been overkill and if I do it again will use a 2.5 - 3" cut and try to squeeze it in a smaller chassis.
Also, I mentioned it earlier, but the thread over in the ChipAmps forum has a lot of good information. My build along with a couple others are posted in it and it answered a lot of the questions I had.

Thanks for the info.
I have some of the 5.375" but were cut to 8" long. Classic case of whatever you have never fits 😀
Just a quick update that I did receive mine last night. The black PCB is pretty sharp looking. It's a toss up to which looks better, the black or the blue that I had previously built.
Go into Paypal and check your shipping address. To me it looks a bit suspect. If we are lucky the letter will be returned after four weeks. The address goes to a shopping mall? (According to Google)
