Are these normal temperatures for i5 4670k with water cooling?

So I have this i5 4670k non overclocked yet. I installed water cooler (Raijintek TRITON) but I'm getting tempereatures which make me doubt whether I installed cooler correctly. I unmounted it and mounted it back for 3 times, always getting same temperatures. My temperatures on idle range from 35-42 and that seems quite high to me. What do you think?

I applied thermal paste 3 times, 3 different ways:

1.) I spreaded termal paste with credit card
2.) I did it again, applied slightly thicker layer
3.) applied only a "pea size" of thermal paste in center of cpu and let it spread itself when installing cooler.

It's probably worth mentioning that when I spreaded thermal paste with credit card and installed cooler I noticed that when I took it off there was no trace of thermal paste on some parts of nickel plated thing on water cooler block. So I assume it didnt get in contact on whole surface

I did apply more yes, since the first time it was too little, because when I spreaded with a credit card, I could see a "writting" on CPU through the layer of thermal paste.

And I can't tighten the cooler in a cross pattern because it has only 2 screws (http://www.play3r.net/wp-content/uploads/2014/09/CPRT_012_8g.jpg)

And as much as your question sounds dumb, but it really isn't because the first time I installed it, I forgot to plug in the pump.^^
But to answer your question, yes, both, the fans and the pump, are plugged in :)

also, what is the true definition of "idle computer"? Does moving mouse, have Steam opened in background, etc have an impact on temperatures? Because when I turn all of these OFF, my CPU idles at 25°C

Honorable
idle is when it is doing nothing. 25 degrees is a good idle temperature. In regards to seeing the writing this isnt a bad thing, you want practically the thinnest layer of thermal paste that will cover your cpu possible as it is there to fill the imperfections in the ihs and the baseplate (or waterblock in this case).

When I run realtemp, and open task manager at the same time, something bugs me... Realtemp shows "Load" jumping all the way from 3% to 25%, and clock jumping from 800Mhz to 2000Mhz while I'm not really doing anything and Task manager shows load from 2-3% without any significant jumps. That's why I asked whether my computer really is idling or it isn't
