Hey guys, just wanted to get some input on why my heatsink isn't keeping my cpu temps lower then what they are.

Currently the heatsink is keeping my pc at 25-30c with 1% load. When it jumps to 100% on stress tests, it goes up to 70-78. I don't get why its running so hot, the heatsink is a good quality so i don't know why its not keeping it cooler..

I did have to disable the top 200mm case fan, because a blade broke off and was causing my tower to vibrate. Could that be why the temp's are a little hotter? Any feedback would be appreciated, I have read that other people using the same heatsink are getting 40-50 C under 100%.

My CPU is sa i7-3770K. Any help would be greatly appreciated.

Other people getting 40-50C is probably when their CPU is at stock frequencies. You're currently running at a 600 mhz bump, which, while not extreme, is still nothing to sneeze at. Regardless of how much voltage you are using to feed your CPU, that is more than likely the cause of your excessive heat.

However, like said before, if that 200mm fan was your only exhaust, that could be contributing to the heightened temperatures. Depending how the rest of the airflow in your case is, having a lack of exhaust could add as much as 10C.

If the 200mm fan on top was the only exhaust, that could help to explain why the heat build-up was so bad, but I do not think it would be the cause. (What is your ambient temperature?)

Do you have Turbo Boost engaged? Or some other form of auto-overclocking on your motherboard?

Turbo boost is set to auto, I have the multipliers at 41, which is not even that big of an OC. My idle temps seem like they are to high, sitting at 27-30c.
I don't know how to measure the ambient temps? I am pretty new to the hardware aspects, so could you explain what that is and how i can find out?

EDIT: Ok so I figured out what ambient temperature is. My home is set to 21C, but I usually keep the window open in my room. My PC however is not on an elevate surface, which could be causing the temperature to be a bit higher inside.

Yeah, I am going to order a new 200mm fan , and install it and then check the temps. I am certain that is attributing to the added temps. In a month or 2 though, i am planning to go with Corsair hydro series cooling for my CPU. If i do get that cooling for my cpu, would i be able to add a waterblock to my gpu as well? or is that not part of the hydro series?
