High Temps using Thermalright Ultra 120 Extreme

hI guys,

I've been having some problems with my CPU temp so I decided to invest in the Thermalright Ultra 120 Extreme.

I've clocked my i7 920 bloomfield up to 3.2ghz from 2.8. However, I am still getting idle temps of 46 - 50 degrees C.

I've applied a very thin layer of thermal paste to both the cooler and cpu and ensured it's tightly fitted.

I've also replaced all my system fans with some Akasa Viper Fan's. In all I've spent 80 quid to better my cooling and my system is now loader and no cooler than what is was before.

I'm using a Lian Li PC-B10 case btw.

Any ideas on what I'm doing wrong?

Thanks!
 
What are the full load temps like?

I had a TRUE on my system and was getting 45c idle but I was overclocked at 4ghz.

Maybe a case of too much paste, as you say you applied a layer to both. As mentioned, what are your load temps like. Prior to my current prolimatech supermega i was using an ultra, it was actually a slightly better cooler than what i have now.
 
Pretty poor for 3.2, what fans? Also as said above, i'd put a pea sized blob of TIM on the middle of the cpu and press the heatsink into that to spread, no need for both to have TIM. I've used a lot of TRUEs on 920s and had excellent results up to 3.8-4.2GHz.
 
76c on highest core at 4.0ghz under a TRUE was what i was getting. In an akasa eclipse 62, which hadnt great cooling, what sort of voltage are you putting into the cpu for that overclock?
 
cpu voltage in the bios reads 1.3

After running bf3 for a while and getting the 80degrees temp I did a restart and noticed in the bios it was only 45. Surely it couldn't cool down that quick?
 
1.3 is way too much for a 3.2ghz overclock, i need that at 4.0ghz. Drop the vcore to 1.200, test with LinX/Intel burn test. 20 passes should be a good test. If stable, lower the voltage again, iirc my 920 in sig went all the way to 3.6ghz on 1.18v, off course your cpu will be different. This will help bring your temps down a bit. A reseat of the cooler may be required as well, as any stress program will load the cpu more than any game, and your hitting 80c in game already.
 
I lowered it to 1.8volts, now running 3.21ghz. My temps are reading 74degrees max when running Prime for 5minutes.

I'm more concerned about the 45degrees idle temp. Maybe there is too much thermal paste. I'll scrap some off and see if that helps. The True is a bitch to install in my case tho! :)
 
I hope you mean 1.18v.:D Try remounting the cooler, and just use a tiny rice grain sized blob of paste on the cpu. Also make sure that your case has good unobstructed airflow, and that your fan/s on the cooler are ramping up properly under load. 45c at idle is a wee bit warm, but load is more important. Besides it could have more to do with the room you keep your rig in. Personally i cant stick too much heat. Therefore my system idles at 38-33-38-33 ono as the room is pretty cool.

haha yes I did mean 1.18v.

I remounted the cooler and put only a small drop of paste on but I'm still getting idle temps of around 43 - 45degrees. I can wiggle the heatsink a bit but I'm using the spring loaded screws so can't exactly tighten any more than I have. I'm not sure if this is normal!?

Do you think I can lower the voltage any more than 1.18 for a 3.2ghz overclock?

I'm using an asus rampage ii extreme and the only number I changed was the CPU voltage in the bios. Not sure if there is anything else I can alter to bring the temps down?

thanks again

try and apply it that way
 
Hey,

I've applied the paste in all different ways I can think of but I don't think it's that. It is a very thin layer that's evenly spread.

I did notice that my qpi/dram voltage was set to 1.3 which i lowered to 1.18 but for some reason that increased my temps by 5degrees.

cpu pll voltage is set to auto!

I'm new to overclocking so don't rly know what these means (will do a bit of research), i've always used the auto feature in the bios.
