i7 3770k 1U HSF

I am having difficulty finding a HSF that is rated above 73w.
I need to get at least 77 watts for the new Ivy Bridge CPUs, any ideas...?
Have already been told Dynatron will work fine, but it;s rating is 73 watts, which means I am not matching it, nor adding headroom.

Thanks JAV

Dynatron is almost certainly your best best. However, you must be refering to the K2 fan. Look at the K199 instead. It has a larger higher power fan, and it's rated for 95watt! http://www.dynatron-corp.com/upload/Downloads/K199.pdf

Probably your only other alternative to to do a passive 1U heatsink with ducting and remote mounted blower/fans. Obviously the case needs to be set up for that but would certainly give you more thermal dissipation overhead if you can do it.
 
Thanks there Chief.
I was looking at that model but it didn't show the wattage until I saw that pdf. file.
This is great news as I want to OC slightly, not much.
I have a 1U DSP where 18 x DSP Chips do the number crunching, but I use maximum RAM for audio targets that turn around and stream random reads form SSDs.
But I have read the IB's get hotter than most CPUs so my little 3-400MHz won't hurt too much.

Cheers.

Good deal. As long as you don't mind the noise. The 1U fan is not going to be at all quiet when it spins up!
 
Yeah... I have to build 5x 1u render farm using i7 3770 processor... so I'm looking everywhere to all the info. What 1u case did you used?

why does it have to be the 3770 processor?

Why not just getting a Dell C1100 /w 2xL5639 hexcores + 36gig of ECC RAM package on ebay for less then 500 each?
In the Ebay search field, type C1100 L5639 and u should get a boat load of hits with price tags varying from 450 -> 700 (depending on how much ECC RAM)

That package is a 1U + fully assembled minus HDD + Has ECC RAM + 12core /24thread box that draws a little under 240W fully loaded each.
Get a Server Rack to store all 5 1U assembly's and thats LESS work on your end in setting up hardware.

How is that package any less superior to you getting a i7-3770?

I already have 16 Dell R410 servers :

  • Dual Xeon X5650
  • 64 GB Buffered ECC 1333 RAM
  • 900 GB SAS 10k RPM
We found that Core i7 3770 are about 30% faster in our render farm. Probably caused by the NON-ECC Ram. And they are less expensive.


We dont want to buy used computers since we need some stability.

then your most likely gonna want to get a 2U case instead of a 1U.
Reason i say that is because your gonna run into problems with cooling the board and heat sink unless the board itself was designed for 1U applications.
 
You might be right... but where is the challenge ? 😉
Hopefully the cooling on this case is enough... I'll test one unit to be sure.

My plan B is a 2u case but its not ideal, server racks aren't cheap.

I'll keep you guys updated on my tests.
 
if the 3770 uses the larger intel heat sink.. the one which the fan is higher then the back IO faceplate... it wont fit. :T
And even then ur gonna need loud delta 40mm counter spun fans to drive enough static though the server style LP heat sink.
And then... if your board isnt setup right... your ram will suffer from overheating... and... lol... the list goes on and on...

And trust me.. ive been looking for opposite solutions as you are... im trying to take my server out of its 1U case... and dropping it into a 2U.

Only cuz i cant stand 40mm fans... and u cant avoid them in a 1U.
