My first OC, always space for improvements!

post #1 of 3
Thread Starter 
(am i even posting n the right place >_< )This is my first overclock. I need some help with the cooling side of things.. i have one annoyinggly noisy fan (one at the back?) apart from that it's pretty damn quiet! heres my spec:

CPU: Intel Core i5 661 (3.1 Ghz) OC'd to 4.2Ghz (I'll post a CPU-z thingy with this)

MB: Gigabyte H55M-UD2H
PSU: 550W (no idea what the company is)
Case: some cheapy case
HD: Samsung Spinpoint 7200rpm 1TB
Cooling: Arctic Freezer Pro 7 rev.2 (modded, see pics below)

That's about it.. =/
Northbridge was getting a bit too warm so put a tiny fan infront that blows air on it.
I've used Real Temp so far to keep an eye ontemps. Happy so far (on stock 3.33 Ghz idle was 17C). Atm on average use its 30C (OC'd to 4.2) is there any way to get it cooler? i know adding a GPU will turn off the graphics core in the CPU and let it run cooler but i'm having budget issues atm.. and theres no space to put the GPU =/ i've set the CPU core drive thingy to 1000mv (or uV??) and multiplier to x26 (that's the max). Out of curiosity, what is CPU clock skew?

Inside:


CPU Cooling (two extra fans are intel i5 stock fans. both at full speed):


Northbridge cooling (necessary?):


Feedback appreciated! cheers =)

oh and what's the furthest i can go with an OC without blowing things up..? i know 4.2 is alot but i like to go extreme xD

you do know that isnt the northbridge dont you? thats the southbridge. your northbridge will be under your massive heat sink. the southbridge does not have a sensor so youll have no idea what temp it gets too. your northbridge is fine to 70*C before id worry about it too much. also those fans you have attached to your cpu heat sink will do next to nothing, youd be better off getting another arctic cooling fan and sticking it on the other side of the heat sink so it sucks the air out. that way youll have a push pull setup and more airflow. attach another 80mm fan sucking out of the case on the back were you have an empty place.

actually i do think it's the northbridge =/ when building it i was actually looking for a southbridge, couldn't find it! no chip under the heatsink either :S (pic of bare mb below, reckon they put two in on?) i'll be getting rid of the tiny fan then. The chip does get pretty warm though but nowhere near 70C. i was thinking the same about the two fans too, reckon making a sort of duct using cardboard and sellotape and sticking one or both the intel fans on the other side blowing out would help? true push pull setup that way..
