It's not the horticultural crap that matters, it's that they list PPF of their other cobs to compare. Maybe they were great, who knows, but with logic like A-PPF, I'm not so sure.

Guys I want to run the citi 1212 at 1050 do you think this will keep it cool ?
http://m.servershop24.de/item/32373638
Its pretty heavy 700g each and has a copper base plate of 1/3 inch.
Here are some more pics

Going to run 60 pieces of them I will also put one big blow fan at the wall for them.

That looks like it wouldn't work without a fan, and with a fan would be overkill...so maybe?

Then maybe 700ma more spread better effi and lesser cooling.
Hampster you mean with ore withouth fan ? Have you worked with these heatsink ? 1050 = 36w 700ma= 24.4w so not 50watt

It needs a fan because of the design. It will act like a solid hunk of metal without some airflow. You'll notice passive heatsinks have wide fin spacing, CPU coolers are much more tightly packed. Natural convection stops happening with close spacing.

I can cut some fins NP
I understand what you say I looked at the alpine m-1 passive it keeps a 35w at 49celcius with only 250 gram of alu.

But like you said the fins have more room for air between, i need to cut some of that heatsinks

It's not passive.

Before I make my decision to purchase can you confirm whether the 120w dissipation is active (with fan) or passive. My intention is to use this heatsink to cool passively, without the use of fans,

Hello,
the heatsink is passive. And it also fit only in the mentioned HP models like DL380 G5 and DL 385 G2 / G5. The heatsink is own-production from HP. It can not be used universally.

Maybe the clu058-1528 is a better choice for me and rund them high and just use a cooler with fan.
Can I run 4x clu058-1528 at 2100ma on one ?
http://en.hzzhpower.com/upLoad/product/month_1601/PF-P400CC-Cxxx-S(U)-XX.pdf
On the citi pdf it says that the voltage is between 47v min to 56v max. If its 2.10x47= Then its oke but if more then 49v then its to much

No he said inside the hp box and normally there allot of fans in a server box. It has 2 for each cpu

I don't know what the 1528 is, but the voltage lands where the voltage lands. Google "forward voltage".

I think you're forgetting the 6 2" fans mounted to the front/back of that server case (and the power supply fan) that create a dedicated channel of airflow through the case and over the heatsink so it's not really the same as getting hit once every 10 seconds by an oscillating fan.
I know of no HP server (standalone/rackmount/blade) that doesn't sound like a 747 starting up due to fans.
That said, you could mount the heatsinks in a 5" rail with a fan on one end and simulate that type of design for airflow over multiple sinks and keep them well cooled.
EDIT; Forgot to say thanks to Jorge for his research into Citis!

Would your mind change if the 1812 was $15-16? It's 98-99% of the 1818 below 50W, and destroys the 1212 above that. I'd say it's worth an extra $3, personally.
Heck, I'd happily replace my 1818s with them at the 700ma I run. There's only 2lm/W difference.
