[Solved] SPOT THE DIFFERENCE: Xeon L5420 VS Xeon L5420!

H!

I wanted to buy a processor that would take wattage as much as my current E2140, but would be a quad core. And I got one-- the Xeon L5420!

But at the new egg, I found two entries-- same price. The only difference between them is the letter "P" instead of "A" in the model number:

BX80574L5420A
http://www.newegg.com/Product/Prod [...] 6819117169

BX80574L5420P
http://www.newegg.com/Product/Prod [...] 6819117170

Of course, this small change also means a change in the actual product, however small it may be. And the change is, that the A comes with a heat sink and a fan, while the P comes only with a heat sink.

Now here are my questions.

Q1
Is the A model, a better version with the fan along with the heat sink, and this is the one I should buy?

Q2
Is the P model, an advanced version of the A model, like the latter letter suggests, in which the fan was removed because this CPU model heats less, and probably the fan made noise?

Q3
Would the P model require me to buy a fan separately for the CPU?

Q4
Never heard about these ones. Are these discontinued models?

I was very happy, if it was not for this confusion, because all the AMD quads equivalent to this one seem to come without the cooling device, while spending at least some more watts.

EDIT:
I shall use my computer for mainly gaming, with the Sapphire 4870 I have. Hope this would be a good quad core for this, serving me for a few years. (Yeah, I know I would need to change my 945G, the LGA 775, motherboard.)

Thanks

Here is the site showing all of this. It also appears the coolers are shown at the bottom.

What EXT64 meant was the air-tunneling effect when utlised with a 1U or 2U chassis (depending on which bundled HSF) would be gone when used in a typical tower case.

Then you have clearly wasted some serious money there.

Will the Xeon work in your motherboard? what mobo is it you're looking at getting?

Have you looked at the Q8x00S chips for low power quads?

I guess you missed the part where he said he would be using it for gaming.....

GOT IT! GOT IT! GOT IT!

We hereby declare the current project of buying myself an L5420 as null and void, and hence shelve the project. We hereby thank all the candidates for saving the buck and shattering the discovery that we had found out one hell of a chip for gaming, which turned out to be a joke, that also a dumb one.

New tenders are now invited for a new project regarding a fresh purchase of a Q9550 or similar processor for gaming and ripping through the dumb Java and Dot Net applications like Firefox and the Internet Explorer, that take upto half a minute to open for the first time. Though this CPU uses twice the wattage, but now we have understood that that is the best solution in the current scenario.

We may also proudly inform that we had to Yahoo all the terms we were unable to understand, like the "2U rack" and stuff. We must tell you that we were successfully able to find out the meaning of these terms.

^Agreed. Or if OP wants hexcores in 2010 LGA1366.
