I'd like some clarifications on legitimate load temps

post #1 of 10
Thread Starter 
When I first started OC'ing this computer I used only TAT to find my load temps and now I recently read on one of the threads here, didn't want to hijack, that TAT stresses the CPU way more than any game or application can.

Can my load temps be found using Orthos? My load temps with Orthos are 10 degrees lower than my TAT temps which would allow me to obviously OC a lot more.

Thanks

What's the most intense application you run? You could also turn on the TAT log file, play or run that for a while, then look back at the log file.

run orthos for ten minutes, and check the temps on TAT - IMO, just keep temps below 65c and you're all good.

dude, temps are all just safe practice, even if your comp is at 70 all day, I severely doubt you will ever notice anything, you will prob have a new proc by then.

B-80 is right. If you want the chip to work 5-10 years down the road, don't abuse it. If you don't care and will upgrade in 2-3 years, f*ck it and o/c and enjoy it. FYI - Intel's specs on the E6600 have a max core temp of 60 °C if I'm reading it correctly.

But that didn't answer your question: I'd say you do the most CPU intensive thing you will ever do on the machine and log the temps as you go. Do you plan on running orthos everyday? I doubt it. Orthos is good for helping you identify the lowest voltage you can run @ since it reports errors if the CPU becomes unstable. If you're concerned about your temps, my advice is:

1) Get a good better HS. Your P180b will fit an Ultra-120 Extreme which uses a 120mm fan and is likely the most efficient HS on the market today.

2) Lap the HS and IHS on your E6600. Doing this dropped 7-10 °C off my load temps on my q6600 (7 on the coolest core and 10 on the hottest core). It'll cost you under $20 to do and will be the biggest bang-for-your-buck cooling period.

3) Make sure your have good case air flow.

4) Find the minimum vcore you can use for your overclock. In other words, find an o/c you're happy with (9x333 is good enough for me) and then drop the BIOS vcore, boot into win and run several orthos. If it's stable for 5-6 hours, drop it again and repeat. I'd say you'll wanna start at a low value and work your way up since if it's too low odds are you'll crash right away or soon. Took me several times to find that my q6600 running @ 9x333 can do so @ 1.3125v. Lower voltage = less heat output.

<60C loaded in TAT is what you want to achieve.

if this is achieved, in reality this may mean you can overclock a bit further as you'll rarely be gunning your PC 100% for long in most normal use

Thanks graysky for the pointers. I have a couple questions.

How do you determine good airflow? I have all of my major power supply wires being fed to the back of motherboard tray. All-in-all I think I did fairly well for being such a newb. Heres a pic.

No digital so its a cell phone pic.

Also when you lapped your HS/CPU could you give more detail on how you washed them as you were lapping. Also when you said you used gravity, did you lay the sandpaper covered glass on the cpu or vice versa(same question for HS).

Edit: BTW that is a ****ty sound card RIGHT next to the vid card and I do indeed know that is blocking the exhaust. I've got a PCI slot antec blower coming in the mail tomorrow and that sound card is going to the bottom slot.

Well, it's a relative term. You have a good setup with major wires behind the board, cords pulled down out of the way of the airflow, etc. I have seen some cases that are awful with wires everywhere, fat ribbon cable for IDE blocking intake fans, etc.

Here is a thread w/ more details. To answer your specific question about washing. The key is to add enough barely soapy water to the sand paper to help lubricate the item you're lapping as well as help catch the metal shavings you're rubbed off; a little bit on the HS if you're doing a HS and none on the IHS if you're doing it. After you finish lapping in one direction you'll want to wipe the item off with a moist rag to remove any metal shavings from it and use a squirt bottle to clean up the sandpaper, blot it with a paper towel several times and repeat.

As to your 2nd question: I took the glass and tapped it down to my work surface. I cut the sand paper into skinny strips and tapped them down to the glass. The trick is keeping the water away from the tape so it doesn't cause it to lose its sticky hold on the paper/glass. You then take the item to be lapped and gently push/pull it up and down on the sandpaper. Some guides say do circles. I think this is a mistake because when you do it that way you'll have a tough time keeping even pressure on the object and will likely end-up with a non-flat surface.
