Silver Arrow Sandy Bridge High Temps?

[kbk_75]

My i7 2600-K is overclocked to 4.8GHz at 1.4v with level 2 LLC. (1.42v idle, 1.45v load according to HWMonitorPro64).

Idle temps are around 40 C, load temps (Prime 95 large fft test) go as high as 80 C. Ambient is around 30-32 C.

I've never had a quad core CPU before (my last was an E6600 C2D @ 3.46 GHz) and I'm wondering if such high load temps are normal, given my settings or whether, perhaps, there could be a problem with my setup.

The fans are both set to pull, because I couldn't mount the fans above my RAM.

You aren't supposed to go over 1.4 on Sandybridge

If you're using that rig for gaming, I'd try and get that to 4.4 - 4.6 at 1.35v.

You won't notice the difference, and your temps will drop a lot (also set CPU PLL to 1.72v to lower temps).

30-32 ambient is hot - 50c over ambient on those volts maybe about right.

Think of 1.45v on sandybridge as 1.5 volts on 65nm

Thanks for the replies, guys.

I'm not so much wondering what a good overclock would be, or what the sweet-spot for my CPU is, as wondering if my Silver Arrow is actually mounted optimally. The high temperatures are what is making me wonder this. As I mentioned earlier, I've never seen temps this high on my previous dual core chips. I understand that quads run hotter, but is it normal to see 80 C even with a good cooler like the Silver Arrow on a highly overclocked SandyBridge chip?

Doesnt seem too bad to me. I'm using a Noctua dh-14 with an i7 2600k at 4.8ghz. My full prime temps are around 65c to 70c, and my vcore under load is 1.304v. Your temps seem about right to me given your vcore, I would not recommend 1.45v as a 24/7 configuration though.

1.3v @ 4.8Ghz - nice chip. Want to swap?

Yeah, I've scaled it back to 1.35 vCore with level 2 LLC ( = 1.4V under load) @ 4.7GHz.
