DLS2008 Posted November 16, 2008 Posted November 16, 2008 I have a Zalman 9700 on my Q9450 that's at 440x8 = 3.52 and 1.248V (all info from CPU-z). I'm wondering if I need to reseat my cooler because my temps aren't even across the cores. I have it running Prime 95 with four instances using small FFTs and I have Core 1: 66C, Core 2: 58C, Core 3: 64C, and Core 4: 56C. I'm just curious if that's an indication of it not being properly seated. Also, would changing the thermal compound to AS 5 (please give the best compound if this isn't it) from the stuff that came with the Zalman drop my temps. I want to push it up to like 475x8 = 3.80 but I think the temps would get too high. The limit is around 72C I believe and I'm at 66C max load.

I feel that AS 5 is the best but others will disagree it is just a matter a preference. As for the cores being different temps there are many things that can effect temps so as they are not all that different i wouldn't worry about it. You can reseat if you like but its really up to you. Share this post Link to post Share on other sites More sharing options...
dr_bowtie Posted November 16, 2008 Posted November 16, 2008 I really prefer the Zalman Grease that came with the cooler... This is alot thinner in terms of viscosity and can be applied much thinner as well which is very important in terms of thermal transfer... I have used a dozen or so Zalman coolers and in every case the brush-in-bottle Zalman grease has out performed AS5 by at least 2c and some instance higher... I would reseat and use the Zalman grease and also check the contact patch between the IHS and the cooler itself... here is how I do it... Clean both surfaces with Q-tips....I use Goof-off or Goo-be-gone as the initial cleaner... Then I follow up with 98% alcohol (paint store brand) and Q-tips as i will clean the parts until the Q-tips wipe clean without leaving any black on the Q-tip...this cleans the pores as well... then I will shake the little bottle of Zalman grease for about 2 minutes to make sure it's mixed well... once i have it mixed I will open the bottle and clean both sides of the brush on the bottle rim leaving a minimal amount of grease on the brush... I will then use only 1 side of the brush and apply the grease on the core area and just a little beyond...I dont cover the whole IHS as you dont need too... I try to put it on so thin you can almost see through it...I will then seat the heatsink and latch it down and give it a little twist while pushing very slightly down to make sure all the grease spreads out.... I will then pull the heatsink back off and look at both surfaces on the heatsink and IHS and look for transfer pull off...you want even pull off across both surface...alot of hanging pull off means you have too much grease applied and you can wipe off the heatsink and reseat and recheck... if you have spotty transfer pull off with hollow spots your IHS is not flat and may need lapped for straightness... thats it really not much more than that...I have never needed to lap a Zalman cooler...they have all been very flat...the IHS now is another story... and to answer your question on temps... if you have more apps running on one core and not much on the other temps maybe higher on one core....I would check my processes and see if they are evenly split across all core the ones that are running...

DLS2008 Posted November 16, 2008 Posted November 16, 2008 and to answer your question on temps... if you have more apps running on one core and not much on the other temps maybe higher on one core....I would check my processes and see if they are evenly split across all core the ones that are running... Thanks for all of that. For the temps, I had Prime 95 running 4 threads and all cores were under 100% load according to Core Temp.

Fresh2Death Posted November 17, 2008 Posted November 17, 2008 (edited) Hi I'm new here, first post by the way well I have a question, I have a Zalman 9700 in a new rig I built a couple days ago I was wondering if the temps are a little too high its running on a Q9300 @2.50 Ghz everything is at stock settings. I used the thermal grease that came with the zalman I even used AC5 at first but I reset the Zalman with the thermal grease it came with but here is the pic of the temps I wanna start to learn how to over clock my CPU in the future thanks guys for any kind of insite.. these are Idle temps by the way...

dr_bowtie Posted November 17, 2008 Posted November 17, 2008 those are way high for idle temps unless your room temp is like 80f or higher... mine is 28c idle with 70f ambient temps with the fan on low...i'd say something is up...if you put too much grease on the temps will be higher... if you reseat follow my guide very closely in my post above....

I knew something was up but i wanted to make sure yeah I read that post and I didn't do as u said.. but i will follow that now and get back but thanks again!

DLS2008 Posted November 17, 2008 Posted November 17, 2008 Yup, those temps are high. I don't know my true 'idle' temps because, frankly, I never cared. I know that I run steady around 55C under around 40% load with a Q9450 at 3.52 GHz. Share this post Link to post Share on other sites More sharing options...

DLS2008 Posted November 17, 2008 Posted November 17, 2008 well on my Q6700 at 380x10 I never went above 58c with ambient at 70f full load temps after 4 hours of orthos.... that was at 1.475v set in the bios and CPU-Z/OCCT/Everest reported vcore 1.325v Looks like I need to reseat then, my load temps are ~62C averaged across all cores. Plus CPU-Z reports 1.264V. Although, my ambient is about 75F. Share this post Link to post Share on other sites More sharing options...

Well I did everything your little guide said and I didn't get the temps to go down much but idle is now 44,39,39,39, and load temps are 53,48,47,47 I guess I am cool with that isn't as low as I would hoped but oh well..
