Hi guys,i recently purchased the Crosshair Formula V and needed to upgrade my cpu aswell because my old phenom 965BE died because of broken,bended pins.My phenom dropped on the floor because it got stuck to the heatsink when i removed my Noctua...i know..really..i know.Anyway,i needed a fast,and not to costy replacement,i figured the FX-8120 would do well,and was in my budget range.Ive read some bad,and alot of good storys aswell,especially about ocing it easily,wich is a fact,ive never been able to oc a cpu this easy and this high.
Anyway to make a long story short,im not happy when playing games on stock speed with this cpu,it actually has lower performance then my old phenom wich i ran at 3.8ghz.And most of all while all my temps are low the northbridge is idling at around 48 - 50 and shoots up to 60 when gaming.I still oc'd it and while going higher i did not saw my nb temps rise higher then on stock speed,while my cpu temps were going up but stayed well below 50.I can even feel the heat on the right side of my case when laying my hand on where the nb is placed.Im not planning to play games everyday with my nb temp this high.
I saw that alot of other people suffer from the exact same problem on this mobo,but i still want to keep it and the cpu aswell because despite the nb problem i still love both.The highest stable oc i got was 4.6 on 1.38v just by raising the multiplier,and have LLC on ultra high.Cpu temps below 50,but its still my nb temp that keeps hitting 60 when gaming.So ocing or leaving it at stock doesnt do a thing for nb temp,mayb 1 - 2 degress ,even lowered nb to 2000 and lowered volt aswell,it did lower the temp with about 3 - 4 degrees but im not gonna keep it like that.Tried playing with Digi + VRM settings aswell but also doesnt help,only when i let it clock my cpu down ,and i dont want that.Right now im running on 4.0 on 1.37v,multiply x20.
My airflow is good aswell,Got the NH-U12P SE2 on cpu,case fans are 4 blowing in ,and 2 sucking out total.2 blow in from the side,2 from the front,1 sucks from above,the other sucks from behind.Had my case open aswell,tried to change the airflow but it didnt help a bit,the way i have it set now is the best for all temps.
So..i want to replace my Northbridge heatsink,and any recommendations and any help for this board are more then welcome,because i have no idea whats the best northbridge heatsink for this board.

CPU - FX 1820
