Orthos or TAT?

post #1 of 10
Thread Starter 
So the thermal limit on my e4300 is 61.5 C, I know that much. And I know TAT stresses harder than Orthos even though both give 100% load on both cores. I've heard a few people say that most on here go by an Orthos load to see if they are within the thermal limit, and some say to use TAT. That said, at my clock in my sig, stock volts, and the cooler in my sig, I Orthos load at 58 C max, but TAT load at 62 C max. SO the question is, do you use Orthos or TAT (or other) for load temps? Do you think that 2.6 GHz is gonna be the max for my e4300 on air?

Orthos will more than likely stress harder than anything you're going to do day to day, and TAT stresses even harder. I would say that you're fine. Start up TAT and play games, encode video, do whatever you do every day on your computer and see what the temps are like. Playing a game will heat up your graphics card and pump more heat into your case. I doubt they'll even reach 58.

My thought is that orthos is good to stress and see just how high the cores might go. To really see where your computer is going to run day to day just do what you do day to day.

I agree with WED.. Orthos is a better load tester.. TAT is a true 100% load test, and with an oc'ed system that could damage your cpu.. I stress "could"..

But remember 61.5C is T_case max.. TAT/Orthos read DTS.. DTS is about 7-8C higher than T_case.. I have tested about 7 different 4300 systems I have built this year.. They all showed about a 7c difference between T_case(IHS) and DTS..

2.6Ghz is respectable with air cooling.. I have seen only a few that had early production 4300's hit 3.2Ghz or higher on air.. I would have hoped for no less than 3.0Ghz, but 2.6 is still a good oc..

SO you're saying that my T_case is actually 7 C lower than my TAT readings? So really I'm closer to 52 C load? Could you back that up? Because I'd be really happy if I had some more headroom because I too expected 3 GHz from this thing, and am kind of dissappointed.

Don't use TAT for stressing, only for temp reading. TAT stresses the core unnecessarily. Orthos is rather practical. TAT and Core Temp will give you accurate temps.

Read the C2D TEMP. thread found in my sig. below..

The short of it is this..

Intel gives us a max load for ONLY T_case..
That is about 61C for most C2D's..
Intel does not have a DTS rating or max...
Intel flat out says DTS and T_case are not the same and expect T_case to be lower..
TAT/Orthos read DTS...

Speedfan, everest, your bios, and other software read the T_case.. Some software will work better on other systems.. So don't expect all of them to read the same.. Some will work some won't.. Everest worked best for me.. Others use speedfan reading CPU2 i think..

From my own tests on many systems 7C is about the difference between DTS and T_case.. Sometimes I found a 8c or 9c difference... But 7C seems safe..

Speedfan and Everest give me temps below Everest, so I can't use those either. Do you think it would be safe to just subtract 7 C from my CoreTemp and TAT readings? I really just want to be sure...

Yes that is another way to do it.. But just get rid of TAT all together... Orthos Temps and load tester are just fine.. Subtract 7C from orhtos for your rough T_case temps.. by rough I mean a 1C-2C variance..
