Hi sorry for late reply everyone,
Case: Zalman Z9 plus, this case has 3 fans into it
Mobo: Asrock 970 pro3
But will an extra fan to my cooler cool my cpu more? maybe that will resolve the problem
ok what your gonna need if your using the stock crappy paste with that 212 cooler you should get some mx4 that alone will make temps more stable the crap that comes the cooler goes like cheap rubber or cooks and its just bad lol.
remove power cable hold power button down then proceeed to next step
remove cpu cooler and then get the below hardware in
and buy 2 Thermaltake Luna 14 140mm 2 the roof of your case re facing these so they push air out of the case so they should be facing the same way as your rear case fan reasons 1 not pulling in dust into the case 2 not pushing air towards the heatsink but taking out the hot air in the case overall
take the existing top fan off put that to the front of your case ( saving money tactic) this will kick more air into case as well as a added bonus
next clean of the paste of your cooler and chip
clean it of with isopropyl alcohol 99 percent and cotton tips the cooler and the cpu need to be cleaned till looking like new use a small cemaric bowl for iso use a new cotton swab and do not re dip cotton swabs that are dirty into it/ or you will have to empty your fluid out and use that bowl only for pc work in future ( wouldnt recomend using it again eating out of again)
dry with a coffee filter or anti static cloth lint free
use the new mx4 paste you will need 2 pea size drops for the cpu this stuff is thick and use cheap gift card ( make sure its clean best to clean it before use.) and spread the paste with it without lifting up your hand so you have a nice grey layer over your processor no metal should show attach the cooler back on tight and snug the fan path should be facing the rear of your cooler then take a cotton swab dry and go round the socket and around the cooler to pick up any excess paste thats been squeezed out also makes a airtight seal and replace old fan with this
