Systemlord Posted June 7, 2007 Posted June 7, 2007 I have an Asus P5B Deluxe Wifi mobo bios version 1004, Core 2 Duo E6600, lapped Tuniq Tower 120 and my temps are way to high for what cooler I have. My temps at 3.1GHz are 47c idle and 68c Orthos stressed @1.365 vcore with a lapped TT 120 @2100rpm's. I used the grain of rice amount spread it up & down along both core's using a thin layer of AS5 not covering the hole IHS. When watching Orthos do it's thing I see my temps Very Quickly rise in the blink of an eye from idle 47c to 68c stress. I would expect more from the Intel stock HSF with much lower temps. I have great airflow and TT 120 is firmly tightly mounted. This is my first PC build and I'm not stupid as I've done the research 3 months before the build. My first PC build went smoother than I had ever expected from assembly to running! So I please ask for your suggestion's & help. Thank you!

kingdingeling Posted June 7, 2007 Posted June 7, 2007 do you have thermal past in between the CPU and the cooler? If yes, what kind of paste? AS5 would be your best choice! Share this post Link to post Share on other sites More sharing options...
Systemlord Posted June 7, 2007 Posted June 7, 2007 Did you read where it says, "I used the grain of rice amount spread it up & down along both core's using a thin layer of AS5 (Arctic Silver 5) not covering the hole IHS." Share this post Link to post Share on other sites More sharing options...
Bleeble Posted June 7, 2007 Posted June 7, 2007 Welcome to OCC! First of all, good hardware picks. I suggest pasting your system info in your sig so we can see what you're running at a glance. Now, you neglected to mention some important pieces of information: 1. What is your ambient temperature? If you live in a hot climate, those temps could be perfectly fine. 2. What case do you have and what is your fan setup? 3. Most importantly, what are you using to measure your temps? I suggest TAT or Coretemp. I'll try to make a few suggestions base on what you've written... I don't know how much you know, so don't take it personally if I say something that you think is horribly, stupidly obvious. - Clean off your heatsink and CPU using 99% Isopropyl Alcohol and a lint-free cloth (paper towel also works quite well). - Make sure your HSF is actually flat. You can use a flat, unused razor blade on edge. But the best way is to put the base up against a grid like a screen or graph paper and make sure the reflection isn't distorted at all (assuming you base is reflective enough to see anything). Lapping your HS can actually make temps worse, depending on its original shape and the shape of your CPU's IHS. If you're gutsy, go ahead and lap that E6600 too. - Rub a bit of AS5 onto your heatsink and CPU and wipe it off with a dry cloth. (Optional, but I like to do it) - Put a small bead of AS5 in the center of your CPU and put the HSF on, twisting it just a bit as you press down. My E6600 idles at 34C and reaches 57C while running Orthos (Small FFTs, Priority 8); ambient temp is 22C. Frequency is 3.6 GHz (400x9) @ 1.44375V. Yes, I know I've got watercooling, but those temperatures are good for comparison's sake. When I had my Ultra-120, temps were 39-65C (ambient 20) using a Panaflo M1A @ 12V. Hope that helps!

Systemlord Posted June 7, 2007 Posted June 7, 2007 Well my airtemp is below room temp and I have an Asus 3600 Vento gaming case. I have a 120mm 92cfm rear fan running at 2800rpm's with two 80mm in front intake at 2500rpm's, airflow is great because I put a big house fan blowing into the side of case and that made no diff. I am using core temp, Everest, and TAT. All three are pretty close in regards to temps. I'm using AS5 thermal paste and my processer OC'ed to 3.4 with a vcore of 1.375volt. That pretty much tell's me that I'm one of the lucky one's, so I know my cpu is up to OC'ing just have to lap my cpu now, right now. I'll let you know how it turns out. Thanks for helping me, you seem to have great skill's in PC OC'ing. Share this post Link to post Share on other sites More sharing options...
Bleeble Posted June 7, 2007 Posted June 7, 2007 (edited) I'll let you know how it turns out. Thanks for helping me, you seem to have great skill's in PC OC'ing. I'm happy to help! Make sure you post back here when you're done. I want to see your results. ...now maybe it's time for me to lap my own waterblock and CPU...

Systemlord Posted June 7, 2007 Posted June 7, 2007 Well I removed my motherboard, Tuniq Tower 120 and what I found was distrurbing to say the least!! The Arctic Silver 5 that I applyed was not even spread out onto the IHS. It was just where I put it like the two surface's were never squished together, as if you were looking at icing on a cake. So next I lapped my E6600 (say by to warranty) and when I first began sanding I moved the CPU side to side on the sand paper and saw silver dust leaving two lines about an inch apart like your driving in a car with white lines on each side of you. I can't believe how concaved Intel's processer's are, WOW! So next I put everything back together and after all that your not going to believe what my temps are now. My E6600 @2.4GHz with Orthos/CoreTemp stessing both core's are 18c idle in Windows desktop and full load was 30c, never went above 30c. I have included a stress chart that shows motherboard @33c green line and CPU @30c yellow line. Man do I feel really good right now! Also wanted to thank Bleebleand and Kingdingeling for providing me with great high quality help! THANKS GUY'S Share this post Link to post Share on other sites More sharing options...
kingdingeling Posted June 7, 2007 Posted June 7, 2007 do you have pics of the thing looked like? I guess the grain of rice thingy didn't work too well... Share this post Link to post Share on other sites More sharing options...
Ste Posted June 7, 2007 Posted June 7, 2007 Those temps seem rediculious for only 3.1 Ghz. I have a scythe mine, and I had just hit 60C when I was at 3.41 Ghz.. You obviously know the problem by now. The heatsink is not making proper contact with the CPU or even the paste. Share this post Link to post Share on other sites More sharing options...
Verran Posted June 7, 2007 Posted June 7, 2007 E6600 at 30c full load? That's VERY impressive. Nice work with the cpu lapping. I bet you'll have a few other people thinking about doing it when they read this Share this post Link to post Share on other sites More sharing options...
Systemlord Posted June 7, 2007 Posted June 7, 2007 (edited) E6600 at 30c full load? That's VERY impressive. Nice work with the cpu lapping. I bet you'll have a few other people thinking about doing it when they read this You know for my first PC build I have to say, Wow. "If a first time noob can lap both CPU & HSF then anybody can do it." I used 400-600-800-1000 grit wet sandpaper (without water) and used a piece of tempured glass from my hometheater rack for the flattest surface. The reason you should stop at 1000 grit is that the AS5 needs somewhere to adhere to to bond the two surfaces. The first time I put my PC altogether I lapped my TT 120 all the way to 2000grit, but it was so shiny that the AS5 just slid around not mating with the HS surface. You don't need it to be ultra shiny, just flat and smooth. If you thought your Processer was flat out of the box then you might want to have a look a the picture underneath. You guy's should lap you processer's & HSF to. Have a great day guy's beer's on me. Edited June 7, 2007 by Systemlord Share this post Link to post Share on other sites More sharing options...
romeo55 Posted June 7, 2007 Posted June 7, 2007 (edited) Just for a bit of comparison, my e6600 with a Thermal Right Si-128 with a 120mm 40db fan (Plenty of airflow) at 2.4ghz 1.35 (Stock) at load (Orthos) is about 37C on both cores. But I'm guessing because of the smaller core (65nm) the temperatures skyrocket with a very small amount of voltage increase. My current OC (3.5 at 1.51V) gets around 70C at max load (Orthos for 2 hours). Edited June 7, 2007 by The Unforgivin Share this post Link to post Share on other sites More sharing options...
