[SOLVED] Was this a first build mistake or am I missing something ? [CPU HEAT]

I just built my very first PC with i7-4770K processor. Then I attached a 3pin CPU cooler. Under a normal load the CPU temp is averaging around 40 Celsius. However, under a full load the temp reaches 100 Celsius. I just realized that my CPU is heating was due to the fan being in a constant speed regardless.

Should I have bought a 4pin CPU cooler from the beginning or is there another solution ? and if the 3pin cpu cooler can't handle a heavy load then why is it in the marker? It's kinda useless if i'm not mistaken..
 
Some processors are not very strong and need only minimal cooling.
That is what your current cooler was designed for.
Low cost and low capability.

The i7-4770K is a very strong processor and generates much heat when under load.
It needs more than a minimal cooler.

What is the make/model of your motherboard?
Most motherboards will have a 4 pin cpu fan header that is capable of handling either a 4 pin fan or a 3 pin fan.
The cpu fan header is where the cpu fan should be connected.
There will be others that look similar.

In the bios, there should be a section to define a fan speed profile.
Typically, minimal speed then ramping up as the cpu heats up.

Downdraft coolers with small 92mm fans are not very effective and only suitable for undemanding processors.
First of all, verify that your cooler fan is operating.
Install HWmonitor.
It will show the current, minimum and maximum temperatures and also the cpu cooling fan rpm.
My guess is that you should see 700rpm as low and3500 rpm under load.
Something like that.

What is the make/model of your case?
Any cpu cooler needs a source of fresh air to let it do it's job.
You will need adequate front intake fan/s to do this.
Try taking the case side cover off and direct a house fan at the innards.
That will help temporarily.
A decent cooler will need 160mm height. Knowing the make/model of your case can determine this.
Or, you can measure the available height yourself.
 
A 3 pin or 4 pin fan makes no difference.
3 pin adjusts speed via voltage and 4 pin adjusts by timing fan pulses.
Both work equally well.

Your cooler is pretty, but not very effective.
Your processor needs a tower type cooler with at least a 120mm fan.

That's what I thought, but I don't hear the fan ramping up as the temp increases

As others have said, that CPU cooler is way to small. A popular one is the Cooler Master Hyper 212 Evo, which should actually cool the CPU you have. You will need to get a new cooler if you want the CPU to stop overheating.

Thank you.. these are some very valuable informations. The only fans were installed in my case was the cpu fan and the PSU fan with no gpu and an open side panel.
I managed to solve the heating problem by getting rid of my whole cpu cooler. Then I just installed a mini tower two pipe heatsink with no fan. Then I glued a 12mm fan on it. After that I installed two 12mm fans in the fron and an exhaust fan on the back.
My CPU in this configuration survived two Cinabench tests with cpu maximum of 82°C.

Right now all the fans including the cpu fan are hooked directly to the PSU through molex chain.

BTW, My Bios has 4 stages of fan speed, however, the RPM was consistent on 1650 RPM. This is the previous CPU cooler.
