Question: What would be a good replacement for the CPU fan?
Document: After buying many Dell pc's over the years, I was looking forward to finally building my own. Unfortunately just like a previous poster, my pretty blue box arrived with just the fan and no processor. I could swear the box was sealed and showed no sign of having been tampered with. Amazon provided a return label for the fan, but couldn't send a replacement chip, because they were out of stock. I've spent loads of money with Amazon and this is the first time anything has gone wrong.
I would recommend this CPU for anyone because it's speed fast and good for playing recent game very well too.
The Intel Core i7 2600k is an outstanding processor. It's extremely good for multitasking such as ripping videos and other CPU intensive tasks at the same time. For the amount of tasks load, it appears to use less electricity than previous generations of CPU. But in order to use this second-generation i processor you would have to upgrade the motherboard as well because it uses socket 1155. It's not compatible with the first generation socket 1156.
This is a replacement for my initial order. I have built for myself and later upgraded at least 10 computers, all with  Intel procs. This processor replaced an i5 2500, and for the first time I received a bad processor-- the first one just would not boot, I was getting memory error. Thanks to Amazon policies I was able to return the defective processor and had a replacement in just a few days. It installed with no problems and what a difference.
I'm a long-time Intel processor fan, and the i7-2600K no doubt continues that tradition. I don't have anything to add, from a technical perspective, that hasn't already been covered here, so I'll focus on a few things that matter to me.First, I don't keep up with the latest, greatest in computer hardware these days. I needed a new workstation for the house, and this processor looked like it would fit the bill. So far, I've not been disappointed.
This processor is insanely fast! Definitly top notch technology. I made a jump from an Intel Core i3 to this processor and the speed difference is fenominal. If you aren't looking for a gaming computer however I would recommend an Intel Core i5. I took down a star though because one of the features of this specific processor is the overclocking ability and to my surprise the stock fan that came with this processor sucks at cooling it down. I would recommend buying an after market cpu cooler.
It's got all the bells and whistles to make this a powerfully performing, yet energy efficient processor. My only concern is the small heat sink it comes with. I would not risk overclocking with it. Definitely get a proper cooling system before doing anything in the overclocking department, especially if you live in a warmer climate like I do. A good buy. No regrets! :)
The Intel Core i7-2600K has been in service for me for many months now and it runs cool and reliable. No burn ups, no recurrent freezes, no blue screens. Running on XP with a Gigabyte motherboard. No complaints. I realize it is a little out of date now, but if one comes your way at a reasonable price, it would be a good purchase. Definitely recommended. I would buy again if there weren't newer, faster, more powerful CPU's that were affordable.
Superb performance, nicely packaged (although I had no intention of using the bundled heat sink and fan, they were of adequate quality.) I am running Windows 7 x64 Enterprise edition, and the Windows Experience rating for this CPU is 7.8 at default speed. I have not attemped to overclock it yet.
Just a warning for anyone thats going to be buying this from Amazon. I received my package today and guess what! The seal on my Intel i7 box is broken and the CPU is missing!!!!! !GOD I WAS PISSED OFF! But after I contacted Amazon's customer service I was told I'd get the refund after I return it--the box and the fan that is.I really hope someone gets fired over this.
Answer: any 1155 socket /1156/1150  all can work with this
