HI,

I just order via Internet a new Intel Core i7 2600K Quad Core Unlocked Hyperthreading Processor LGA1155 3.4GHZ Sandy Bridge 8MB and I want to overclock it.

With this new CPU, I will get a set of 2 X 4GB DDR3-2133, G.Skill F3-17066 CL9D-8GBXLD but I am still looking for a new LGA1155 motherboard. It is possible that I will wait for the new Z68 chipset instead of going with a P67.

Also, I already have an Hyper 212+ for my Quad Core Q6600 but I want to get a fan much better for my new i7 2600K.

What should be the best CPU fan kit for my new i7 second generation if I want to go as fast as 4.6 GHz 4-Core; 4.9 GHz 1-Core ?

Please refer to http://www.tomshardware.com/reviews/sandy-bridge-overclocking-efficiency,2850.html

Also, I don't want to buy a new fan kit that will be more expansive than my new CPU :??:

Thank you very much for your help

First: While a good percentage of Sandy Bridge processors will do 4.5-4.6GHz, it's possible to get a dud that will only do 4.2GHz so don't count on a specific overclock. About 40% will do 4.6GHz, but only 10% will do 4.8GHz.

Second: When you overclock Sandy Bridge processors, you are overclocking using Turbo Boost. That means your speed won't increase when only one core is being used. It will simply operate at the overclocked speed no matter how many cores are loaded.

Third: Pretty much any performance air cooler will work for Sandy Bridge overclocking.

Some good ones for less than $100:
CoolerMaster Hyper 212 Plus
Zalman 9900MAX
CoolerMaster V6 GT
Thermaltake Frio
Prolimatech Megahalems Rev.B
Thermaltake Silver Arrow

Edit: But with that RAM having its own fan like that, you may want to look into liquid cooling. Most of the air coolers will have clearance issues with that RAM setup. Liquid coolers wouldn't have that problem. Or you could get RAM that doesn't come with a fan.

No, I am not searching for a low cost solution and I understand that Hyper 212+ could support till 5GHz but at what temp ?

I want to go as high as 5GHz or more, if it is possible, but I also want to reduce my cpu max temp.

The only solution I don't want, is to buy a water system @ 200$ or more.

Thank you for your responses.

RAM - I'd run away from that RAM w/ tall heat sinks and fan as it will cause issues with most of the decent air coolers. The days of RAM needing huge heat sinks and fans are long gone. THG tests have even shown that the RAM often runs cooler when the heat sinks are removed. And it's only 2 x 2GB. For $20 more you could have 2 x 4B of CAS 7 RAM which won't bother your CPU cooler even with 4 installed.

The 2600k can be overclocked to 4.6 GHz on the stock cooler. The Hyper 212 Plus is a pretty good cooler for its price. The Scythe Mugen 2 SCMG 2100 is the heir to the best bang for the buck title given it's No. 2 placement here:

Note: I don't recommend using heat sink performance databases based upon the LGA 775 chip set as the heat signatures for the 1155 / 1366 chips vary substantially from LGA 775.

In its other configuration, FrostyTech's Mk.II Platform delivers a 150W and 85W heat load to socket 775 compatible Intel Pentium 4/D/Extreme Edition, Celeron, Core 2 Duo & Core 2 Quad class heatsinks by way of a 30mm x 30mm copper interface die
.

If ya want the best, since the last BMR roundup, the Thermalright Silver Arrow is the new champ. The Collermaster V6 GT beats it by half degree but the GT is soooo loud doing it. Check out this review of the "latest and greatest" here:

The only solution I don't want, is to buy a water system @ 200$ or more.

I was never a fan of the self contained or what I called "faux water coolers", but the Kuhler 620 in the above article is pretty impressive from both a performance and noise standpoint; it would also let you keep that Gskill Turbulence thing. It still won't do anything for your RAM but it does look cool :)

HI,

I think I have now enough info on what fan to choose.

It should be:

COOLER MASTER Hyper 212 Plus RR-B10-212P-G1 "Heatpipe Direct Contact" Long Life Sleeve 120mm CPU Cooler Compatible Intel Core i5 & Intel Core i7

or

COOLER MASTER Hyper N 520 RR-920-N520-GP 92mm Sleeve CPU Cooler Intel Core i7 compatible

I will now create a new post for my new ram because I am not certain.

Thank you for you help.

are you saying that if you increase your multiplier to 45...which should give you a 4.5ghz clock.... that your cpu will only operate at 4.5ghz with all cores engaged? How do you know when the CPU engages all four cores? How do you know which applications will cause all the cores to activate? Do games activate all cores?

and do the processors still go into "turbo mode", increasing the GHz even more?
