Hello im after some advice on OC i currently own a i5-3570k i want to overclock to aroun 4.0/2 GHZ if possible and i like some advice on programs and best cooling method currently i have 1 intake fan and 2 outputs and obviously cpu fan ea fan is 1500-2000 rpm max need anymore info in order to help answer my question please ask in reply
P.S this is first time OC for me
What motherboard do you have? How you overclock is pretty much dependent upon that.
What brand / model CPU cooler are you using?
First of all if you are going to be overclocking you should get yourself a voluminous computer case - personally I really like the CoolerMaster HAF XM. The reason for this is because smaller cases allow for pockets of air to be trapped which will greatly increase your heat problems overall. You need to have a good airflow and above all that, airflow has to reach every nook and cranny of the case. I have both the CoolerMaster HAF X and HAF XM, I am hard pressed to say which I like better, but if I were forced to choose - with a gun to my head - I would go with the XM. The other thing is that you should have a case where you can mount the PSU at the bottom - so that should be one of the main criteria for choosing a computer case.
You will need a good PSU which provides stable power to your motherboard components. A "dirty" power supply can kill your overclocked system. I have a Corsair AX850 which I am really pleased with.
You should go with a water cooler for keeping the temperature of your CPU down. One thing which is often overlooked is the fact that the capacitors surrounding the CPU socket get incredibly hot and airflow to these MUST be guaranteed. Many non water CPU coolers cover these because they are so massive and effectively insulate them. When capacitors reach 200 degrees Celsius they will break with a loud "CRACK" and that is game over for your motherboard. I have a Corsair H80 to which I have attached two Noctua NF-P14 FLX Vortex Control 120/140mm fans. I have mounted the fans so that they blow air out of the case (and not the monumentally stupid way Corsair recommends i.e. blowing outside air INTO the case - I will explain later why). The nice thing about these fans is that although they are 140 mm they have a 120 mm mount. I have attached the H80 and these fans to the rear exhaust and the overhang of the fans supply some more airflow to the capacitors (I have two 200 mm fans exhausting out of the top of the case. The H60 is also a good water cooler to take a look at. I would stay away from the Corsair water coolers that have the letter "i" after them because they seem to be causing quite a lot of problems. I have no personal experience with any of the other water coolers offered by DABS so I will leave it up to others to recommend them or not.
As to why the recommendation made by Corsair to mount the fans so that it is blowing air into your case is stupid; you may think your house is clean, but don't dust for a while and look what accumulates. If you have your fans set up the way Corsair recommends then you have basically installed a dust magnet onto your radiator, so you have a really nice gooey mess accumulating in the radiator over time and of course the pollen will make matters even worse - "Yeah lets just add one of the main ingredients of honey into the mix of stuff getting sucked into the radiator, what could possibly go wrong?". The liquid circulating in the radiator transfers the heat to the radiator veins and the airflow is supposed to then transfer the heat away from the veins. Good luck with that if you have essentially clogged the thing up with something with the consistency of Play-Doh.
Make sure you apply a very good thermal compound between your CPU and the cooler. DABS sells "Arctic Silver 5" but I like the "Arctic Cooling MX-4" personally. With thermal compound more is not better and if you have never applied the stuff before, there are a number of good videos on YouTube that you should watch BEFORE you attempt to do it for yourself.
You should really ask yourself why you want to overclock your system anyway. Is it just for the lolz? If you want to increase the performance of your games you might want to check out a post I made on the thread Dunc's Den entitled, "Getting something for nothing - yes that does exist" which will give you more of a boost than any overclocking of your CPU.
Above all else if you are overclocking then do it gradually letting your system run for a day or so on the new settings before increasing them. Test out what various things you do with the computer do with regard to your CPU temperatures. You can do this with a free program called "Core Temp".
Always and I repeat ALWAYS take any posts you see with regard to how high others have managed to overclock their systems with a large grain of salt. The temperatures they report could be just outright lies, however the ambient temperature of the room where your computer is located will also have an impact on the temperatures you see. I have had two spine operations and have other back problems so I keep my room very warm (28 degrees Celsius at least). I have a moderately overclocked core i7 990x and have had it running for a year and a half (I originally had a 965x) and the idle temperature is around 41 degrees Celsius. I had overclocked it a bit and forgotten about it after my last BIOS update and only noticed it again recently.

There was one thing I forgot to add. Before you can add new thermal compound you have to get rid of the stuff that is already on there.
The stuff that works the best is called "Isopropanol" and it has to be 99% pure. Don't waste your time going around town looking for it or going to the chemists, they don't stock it. If you use anything else then it will leave a residue and that will interfere with the efficacy of the new paste. And don't even consider using lighter fluid.
If you go on EBAY you will be able to buy a small bottle of it.
DO NOT leave the stuff lying around if you have kids. It is extremely poisonous. Lock it away, or if you are not sure that a kid will not be able to get it pour the rest away after you have used it. It is easy enough to reorder and you can get a small bottle of it (more than enough to get rid of the gunk on one processor) very cheaply.
The best thing to use is a cotton bud to get the stuff off and then a paper towel to finish the job.
With regard to overclocking a Haswell CPU, if you are really serious about it then the very first thing you have to do is void your warranty.
You may think that you are voiding your warranty anyway if you overclock, however if you do overclock and you fry your processor you can still exchange it under warranty because it cannot be proven that you actually did any overclocking to cause it and so Intel has to honour the warranty.
What I am proposing is that you have to actually take your processor apart. By this I mean you have to take the lid off the processor (known as delidding). There are two methods for doing this, the razor blade method and the vice method. You can look up how to use these two different methods yourself.
The reason is that Intel has put some kind of rubbish between the actual processor and the lid which is supposedly meant to be thermal paste but in actuality insulates the processor and prevents you from overclocking beyond a certain point because of heat. So you have to take the top off, get rid of that rubbish, put on some proper thermal paste (like MX-4) and you will find that an overclock which sent your CPU into a dangerous thermal zone will now run a lot cooler (thus allowing you to overclock even more).
