nb vid:1.1500
I want to aks if they are good and if the temp are normal ? ahh i almost forgot this is with my case opened and the latest bios
what frequencies would u guys recomand me for the stock clock`s ?

That seems really hot for stock speeds.
I get lower idle temps and about the same load temps.
Running my FX-6100 @ 4.7GHz with a 1.52 v-core.
Sure, I have the corsair hydro H60 cpu cooler.
But still, even with stock cooler you should not get so high temps on stock speeds.

My 8120\Sabertooth idles right around 40C as well (+\- 2-3). I haven't checked load temperatures, yet.

Currently: Stock HSF&paste, all power settings off in BIOS, as well as Turbo (running a steady 3.11GHz 24\7, no dips, no spikes) just like computers used to back in the P4 and Athlon XP days.

All of my QFan controls for chassis fans (HAF 922) are set to silent. CPU QFAN is on, set to Normal\Standard.

I had a problem installing this new style of stock HSF. I didn't understand the lever\locking mechanism initially (and the way it looks, you will think you do sometimes), but, managed to install it nonetheless. How the installation went has me a bit nervous about how much the stock thermal paste both moved, and how much really spread out across the CPU.

Thus, I'm not sure if a 40C idle (at full, stock power) is normal, but obviously I'm glad at least one other person is experiencing similar results.

To be safe, I am removing the stock HSF and replacing it with my Zalman CNPS9000 (which is unfortunately a 3pin connector and not 4). I'll be using either Zalman's High Performance grease (which comes in a nail polish bottle and you can evenly brush it on) ((my favorite yet))), or this stick of Arctic Silver 5 I just got with all of my new PC stuff at Microcenter.

I'm probably gonna install with the Zalman stuff if I have enough of it left. Something about a "rice grain sized bead of paste" (or cylinder) spreading perfectly evenly across the surface of a square just doesn't seem to jive right. Or am I the only one still scared not to have the entire CPU surface covered before the HSink goes on?

I'll post temp results up for everyone after I get it done.

I use arctic silver. Just a drop in the middle is enough. It spreads out nice and evenly. I promise. Will probably test the nailpolish model next time to compare. Posting a pic, running AIDA64 stresstest for over 1 hour when the screen was taken. Look at the temps @ 4711MHz. smile.gif

I swear I just read somewhere that something like .003" (three-thousandths of an inch) is the appropriate spec for even coverage across the CPU.

I understand that a little bit in the middle can compress out evenly with heat and pressure applied to it. I suppose it's just more comforting to know that you personally have spread a nice, even layer and got to see with your own eyes the coverage that the paste had when the HSF went on.

I hope Cooler Master is fourth-coming with their case fan specs. I need to find out if the HAF 922's stock rear 120mm exhaust fan moves enough cfms to not be a restriction to the Zalman CNPS9000's fan. If I can't get them both operating quietly, and without restricting each other, I will likely remove the exhaust fan and repurpose it as the Zalman will be facing that exhaust grill rather closely and can simply utilize it as a vent. Any stray hot air from that stream will likely get exhuasted from the top by the 200mil fan on the ceiling (which is also pulling cooler air up from the bottom into the Zalman in the first place).

I sometimes wonder how well the computer world understands the way air and heat move. Some of these new generation cases are really cool, but some, I feel like they have fans to be having fans ("..but, everyone else is doing it!") and not considering things like: cfms vs. rpms, location, facing\direction\flow, pressure zones, etc...

Technically, I'm a car guy on paper. I've only got computer experience by growing up with the father I have. From a cursory glance through the industry, I'd have to say that car guys are a little better with moving air wink.gif

Yes ideally you want a TIM film so thin it is almost translucent. Unfortunately many enthusiasts are unable to do this correctly and end up with WAY too much TIM so TIM makers have started recommending a pea or uncooked grain of rice size amount of TIM in the center of the CPU. While it's NOT the best solution it reduces the problem for many people who use at least TEN TIMES more TIM than required. Over time the pea sized TIM spreads out but may not cover the entire heat spreader, but at least it's not dripping over the sides of the CPU.

TIM is ONLY intended to fill the MICRO PORES of the heatsink base and CPU heat spreader. MICRO PORES are machining marks, scratches, and minute low spots. TIM is NOT intended to be a separation layer between the heatsink base and CPU heat spreader. Metal-to-Metal contact is ALWAYS the best. TIM is a thermal insulator compared to Metal-to-Metal contact so only use a thin, thin, thin, layer of TIM if you want the best efficiency from the heatsink.

First I KNOW WINDOWS EXPERINCES SCORE IS A CRAPPY INDEX. with that being said is anyone scoreing any better then 7.8 with thier chips? I went from a fx-6100 to a fx-8150 and the best I've gotten is 7.8. If anyone is getting a 7.9 could you let me know what clock speed multiplier bios setting ect. your using to get there. I have my fx-8150 on a crosshair V formula board and have been running it at 4.06 ghz. If anyone can compare notes thanks!!!

7.8 is the highest I have ever seen on one of my rigs. it was my intel at 4.7Ghz. that I know of nothing can pull a 7.9 on the CPU score, but as you said its pretty useless but its still fun to look at smile.gif

This; I've done the pea drop method for years and years but have recently preferred using my finger(cleaned with alcohol of course) and spreading the absolute thinnest layer possible. Best temps so far.
