70°C is about 5 above what most consider safe temperatures on 45nm quads and even with your cheap cooler and the vcore displayed on cpu-z, I would expect better temps (unless EIST/C1E is enabled). You say you haven't touched voltages... does that mean you've left them on auto? If so I would try to set them up the best you can as these are the probable cause of your high temperatures.

If you read through some of this thread I'm sure you'll find some settings templates you could work with.

After some tinkering with my new PI's I'm now 4.5/1200 stable, and it's all peachy. The most I've managed to get these up to are 1270 stable, but I hoped for a bit more so I could do some ~1300 benching. Are there any hints jor3lbr / andressergio or others could provide for these sticks? I've tried various ddr voltages and dram ref's but I still fail MT5 when going beyond 1270. Loosening timings to 5-6-5-15 or looser just wouldn't post. Did dram skews help any of you? I guess I could always see how far 4-4-4-10 could take me, but I imagine 1080 would be out of reach for benching purposes.

If I can get these stable beyond 1270, then I will try for 530x8.5 / DDR1272. I got a minute or so of prime out of it, but know the memory isn't stable - the main reason for trying for this is because the system seems so much snappier at this fsb/multi than at 500x9!
