I've been trying to find out why my temps are so high and can't seem to lower it. I repasted and reseated the cooler twice already (was a real pain), but the temps didn't change.
My temps (according to Realtemp, Hwmonitor,etc.) are:
That's pretty normal. If you have Vcore on Auto, you could take it to manual and find the lowest stable Vcore.
I had the same concerns with my i7 4770K with a Cooler Master Eisberg 240L. I discovered that my motherboard was giving my CPU 1.2V in Auto. I was able to get it down to 1.14V with it overclocked to 4.1GHZ (all cores synced). I still want to push higher, I should still have room to bring up Vcore with my multiplier. I don't really want to get above 1.2V for Vcore.
Thanks everyone. The reason I'm concerned is because
1) I have seen other users achieve better temps with the same set up and a few variations.
2) I had this build for a month now. During the first week, the temps were cooler. All cores would idle at 26 to 30c. Load temp peaked at 69c.
3) this is something I really regret doing and I know it was very stupid, but I was very tired and not thinking straight last night. When I removed my the heat sink, a good amount of thermal paste had spilled onto the sides of the cpu. I had to remove the CPU and placed it on the plastic box that it originally shipped in so I could clean the sides. During this process and bring the idiot I was, I took a needle, wrapped it in coffee filter, and used it to clean the edges. I must have tried too hard because the green plate was visibly scratched after wards. Some of the paint was chipped away. I also couldn't get all of the paste off. I'm not sure if this damaged my cpu functionality or not. I'm 95% positive no pins were bent. My temperatures didn't change. Aargh i'm stupid. Sorry if my post made you cringe.
What you scratched is not paint, its the substrate. Consider it a PCB (Printed Circuit Board) that has all the small traces going from the underside of the die (which you can't see because it's under the heatspreader) to the contacts for the socket on the other side of the substrate. You should be OK as long as the scratches didn't go too deep. If it POST'd afterwards your probably OK.
Don't get too caught up cleaning the paste from the side of the heatspreader. Just use a QTip and isopropanal (90%) and remove as much as you can. As long as the paste is non-conductive (ie not Liquid Metal) then having a small amount along the side like that won't hurt anything.
As far as others achieving better temperatures, Haswell more than all others has a wide range of temperatures. In most cases if your temperatures change for the worse over time, it's usually dust building up in the heatsink and a blast of canned air usually sets things straight.
That sounds OK. If you really want to get your temperature down, consider finding the lowest stable Vcore. It definitely made a difference for me when my motherboard was supplying 1.2V in Auto. In your case I don't think you'll get down too much lower, but even if you can get down to 1.05V, that will make a decent difference in your temperatures.
