My brother has a Q9550 that he bought from a user at another forum and it has slight scratches and scuffs. Any way to fix this? He believes he may be getting alot higher temps than he should be!

Possibly some pollish?

Hes getting around 80c at load and 35C Idle. 3.4 at 1.30v
 
The CPU's by default already have some etching on the serfice with the CPU details.

This is what thermal paste is for, it fills in the imperfections when mating the heatsink to CPU. You can look up some guides on lapping a CPU, it's fairly common for hardcore overclockers. Polishing to a near mirror finish.

Idle temps sound fine.
Load temps don't sound horrible considering the overclock, Intel CPU's are highly resilient. But I don't know off the top of my head what to expect from an overclocked Q9550. I tend to watch the DeltaT reported by Realtemp, the Delta to TjMax rather than the abstractly calculated for real temp. I feel TjMax delta gives me a better feel for safe operating range.

An important detail, what cooler is he using?
 
A lot of variables here...

What heatsink is he using? How big are the scratches?

Also what are you using to test your load temps? Like for example, my Q9650, 4.4Ghz @ 1.4v has a load temp of like 75C during Vantage, can get up to 80-85C during Prime95, but if I run Intel Burntest all 4 cores spike to 95C within a few seconds lol. That doesn't worry me since I never come close to even Prime95 temps during real games but it does show that "load" temperatures without context can be misleading.
 
I wouldn't worry about it unless there are big gouges. Those temps sound like the stock cooler.
 
If it is keeping you up nights, google "CPU lapping", 20 minutes with glass from a picture frame and a sheet of 400grit wet and dry sandpaper will make it all better. (write down all the info printed on the heatsink first, might need it someday, unlikely but you never know).

But unless it is badly gouged in a lot of places I dont think a few scratches are going to be the cause of high temps. As mentioned in above post, the thermal compound is designed to accomodate that kind of thing.
 
Sorry for the late response.
