I bought my E8400 in April from Newegg. Ever since then my Core temps have been at 39C for 95% of the 140 days my computer has been running for. It never changes. I know this is a really common issue. I have just been running my E8400 at stock settings inside an Antec 900 case, with an Arctic Cooler 7. I have overkill Case and CPU cooling for stock E8400 settings and i knew the readings weren't accurate, so I didn't worry.

Well I'm in the process of revising my computer setup, and I want to Overclock my E8400. I was basically approved by Intel to RMA my E8400. Since I am overclocking soon, I want accurate temperatures if at all possible.

So my question is do the newest made E8400's still have the same problem?

I searched all over and I couldn't find any info about if they have been fixed or not.

Thanks for reading.



Edit:



Check out these pictures. What would you guys do if you were me? Would you RMA it?

The sensor is perfectly accurate at any temperature overclockers actually care about.
It reads over 44C just perfectly fine, and temp isn't a concern until it's 60+.
So even if Intel approves your RMA, personally I think its a waste of time.

Core temps (Tjunction) are usually 3-5C over CPU Temp (Tcase), so you can usually guess the temp anyway within a few degrees. But it's the load temps that are important, not the idle temps.

Sounds like a waste of time to me.

I looked through the most recent Newegg E8400 reviews and I found that the last review in which someone mentions getting an E8400 with a stuck temp sensor was 2 1/2 months ago(mid-august). There have been around 80 reviews since then without any reports of stuck or faulty sensors.

I think I will RMA unless anyone has something to say.

1. Download RealTemp and run the "Test Sensor". That way, you actually know it's a sensor problem and not a mounting problem.

2. IIRC, Newegg doesn't accept RMAs for CPUs after 30 days.

1. I have already done that. I've used RealTemp for a long time.
2. I didn't say Newegg was accepting the RMA, I said Intel was.

But I appreciate the response. Thank you.

Thanks for the response. I think you're right. The CPU has performed great, and it appears to read accurately over 39C. Is a 1-2 week wait really worth possibly the same outcome, or worse? I don't really think so.

Yeah mine sticks at 42, despite a moment of confusion (before learning about the issue), hasn't caused me any grief.

Good luck with your overclock!
