I have my i7 950 running at 4Ghz with 20x200 1.325V and the temps normally sit (while stress testing) around 80-93C. Its heating my room up like a mofo-_- Is there anyway i can lower the temps I have reseated the my heatsink (h50) a number of times using diff techniques but they allways stay the same.
Apart from buying a new heatsink are there any other ways on lowering the temps? Ive heard lowering the multiplyer and rising the BCLK can sometimes lower temps. -_-

P.s my case is an antec 1200 all fans are on max and the h50 is in a push and pull config.
 
Just tryed lowering it but it hasnt changed temps maybe by 1c. I lowerd it from 1.88 to standard (1.80) :( seems to have heated up since i went from dual ram to triple ram. I may splash out and get a better air cooler. I think this h50 may not be working fully -_-
 
You should be able to get 4.0ghz on 1.25 vcore If you tweak your settings. I came aross this guide for my Asus P6X58D-E and i7 920

I got bsod death after 10min of prime95 runing using them settings so i up'd the voltage abit on the QPI/DRAM Core Voltage and it became stable. I was geting around 79c max on prime95 using a Titan Fenrir Evo
Personally i think 3.8ghz is best because it uses a lot less voltage compeared to 4.0ghz. I was able to get 3.8ghz on 1.15 vcore.
 
Now people are moving on to SB loads of in depth details on overclocking Bloomfields.

:)

Had the same problem with my H50/Antec 1200 combo in the config that you have... ended up binning it and returning to a really good air cooler (Silver Arrow) which is quieter and cooler by 20 odd C on the H50 on full load. Currently sub 60 on 100% load as compared to 80+ on H50 :)

my current starting template for 3.8Ghz is

Just tweak the CPU voltage down until it fails then knock it back up a notch again.

Let us know how you go. :)

thanks guys :) Ive just tryed the above settings but both bsoded after 2-3mins on prime they both also sat around the same temps. I think like you said above get a new Air cooler. Im a bit worried about getting one that will fit tho. :( ILL POST A NEW QUESTION ON HERE NEARER THE TIME ASKING ABOUT WHICH IS THE BEST ONE FOR MY MOBO/CASE/RAM sorry caps ><
 
I got same temps as you adam when at full FULL load ala Prime using H70. The only time temps are ok is when I've just got up & my front room is freezin cold. When the room has warmed up (fire on) at a nice 24c, my idle temps are around 53 on core 1 to 49 on cores 3 & 4.

have you got two fans in push/pull config,ive just fitted two akasa apache fans on my h50 and at 3.8ghz with ht on im 31c idle and 60c load with prime

same here really. when i have fire on it does get upto 50ish idle :(

you got hyperthreading on? If so, turn it off and reduce volts :)

Just looked in bio's and cant see that option? :( I thought that would slow down the cpu tho?? (or am i wrong?:( )


Also i just turned off Intel speedstep. Is that a good idea or not? it was enabled but by the description in the manual/mobo it sounded like it would cause problems -_-

By turning off hyperthreading your are reducing the performance of the cpu. For multithreaded applications the performance hit will be greater disabling HT than it would lowering the overclock to bring temps back in line.

CPU Vcore has the greatest effect on temps, follwed by QPI/vtt and then CPU PLL and obviously the clockspeed itself. If you are sure your case airflow and your HSF mount is good then try adjusting those voltages to reach a temp you are comfortable with.

You're right, but what if the OP only really plays games? Then the performance drop would likely be negligible compared to the lower temps.

Exactly. I tend to have a few BIOS profiles saved and load each one depending on what I'll be doing. HT really bumps up my temeratures quite considerably. Playing games I'll have HT off @4.4GHz (max temp 72 during Prime95) and with HT on @4.0GHz temps reach 84 during Prime95.
 
If he is only playing games then the liklihood of the cpu reaching anywhere near the temps it does in prime negates the need for him to lower temperatures in the first place, i.e it won't so he doesn't need to ;)
