Recently I just built my own computer. However the temperature of my processor becomes very high and my CPU fan is not able to cool it off when I run multiple programs.

MY CPU temperature can go as high as 85 degrees celsius and it is definitely not good. My CPU fan speed can go as high as 2419rpm only at 100%. I believe normal CPU fans are supposed to run faster than this at 100%.

I have just bought the i7-3770K processor from Intel (Less than half a year) and can I claim the warranty if the fan is faulty? Is this normal and I should buy a better CPU fan?

Probably the thermal paste. Did you apply it yourself? – Martheen Cahya Paulo Jul 7 '13 at 9:23
85C at peak load with stock clocking, stock voltage, and stock cooler is perfectly normal, assuming you're talking about the die/core temperature, not the spreader temperature. The CPU has Turbo Boost 2.0 and will raise its clock speed if it's not overheating. The die doesn't overheat until about 97C. (The case overheats at 68C) – David Schwartz Jul 7 '13 at 10:13
Perhaps you should invest in a decent CPU cooling solution, stock coolers are pretty bad. – cybermonkey Dec 29 '14 at 21:50

Nope, 2000 rpm is quite normal. My PC fan goes around 1500 rpm.

The problem might be that the fan isn't installed properly, or the thermal paste is too thin/thick, or some other problems.

the thermal paste comes with the heat sink, there is no need for me to apply. Is it I have to buy extra thermal paste and apply on it? – Chan Jul 7 '13 at 12:09
Of course that thermal paste comes with heat sink/fan. So, you may not have to apply it by yourself. Then it must be something about the fan no contacting your CPU properly. I had a 775 cpu years ago, it runs at 50C idle, i thought that was good until I install the fan properly and apply some more thermal paste. It goes 36C idle. – Shane Hsu Jul 7 '13 at 12:14
Okay, ideally my CPU runs at 46C with CPU fan speed of 1413. I have checked and the fan is tightly installed. It may be of lack of thermal paste, will buy some and apply see if it helps.. – Chan Jul 7 '13 at 12:32
no overclock right? – Shane Hsu Jul 7 '13 at 12:34
Nope, no overclock. – Chan Jul 7 '13 at 12:49
