Hi,

I recently upgraded my motherboard and processor to an Asus Rampage IV Gene and Intel Core i7-3820 (LGA2011) respectively. I bought an intel fan (Thermal solution RTS2011AC) for the CPU.
The CPU temperature seems a bit high during idle, with the cores being around 45 degrees C.
The temperatures increase to around 55 at 10% load and around 65 at 20% load. These temps seem a bit high to me so I was wondering if this is normal? If not should then should I buy a different cooler for the CPU or is there anything else I can do to lower the CPU temps?

I tried to adjust the fan speeds in he BIOS but couldn't find the settings to do so. The CPU fan often speeds up when the temps of the cores go up but because the temps fluctuate a lot it means that the fan speed goes up and own in a rather annoying fashion. Could I stop this by setting the CPU fan speed to a high value so it doesn't have to fluctuate so much?

Thanks for reading and any help would be very much appreciated.

The LGA2011 i7's don't come with stock fans apparently. Well mine didn't anyway.
So I bought an Intel stock fan.

Ambient temp is just room temp so like 20 or so degrees C.

I applied the thermal paste (just a small line). Though I had trouble getting the fan to screw in properly so I had to readjust it quite a few times. I'm not sure if this may have affected the paste (air getting in there etc)?

I was also wondering whether or not this could be due to the fan not being screwed in properly or as tight as it should be.
I always figured that if it wasn't then the PC wouldn't boot up to begin with? Any clarification on that for me please?

I reapplied the paste and it seemed to drop the temp to around 35-40 degrees C at idle which is great.
I did this downstairs where it's cooler.

But when I moved it back to my room, the temps are now back up to 48-50 at idle.
I mean, it's a little hot in my room but it's not that bad and very bearable.
I don't know what the temps are downstairs or in my room, just that my room is hotter than downstairs.

I'm confused about what has caused this huge jump in temperature. I know room temperature can affect the temp of the CPU but 10 degrees difference seems quite excessive.
