High idle to load delta...what next?

[edouble]

Idle:
Coretemp: ~40C
TAT: ~42C

Load:
Coretemp: ~71C
TAT: ~70C

Load using TAT, 100%.

Orthos (large FFT) is ~26C idle to load delta.

Um...time to reseat the heatsink? Time for a new heatsink? (I have a Zalmann 9700 LED w/ Ceraminique)

Ambient = 22C

E4300 @ 3.2ghz (vcore 1.425)
2GB DDR2 PC 5300
GIGABYTE DS3
CORSAIR HX520
PNY 8800GTS

Reseat the heatsink. I was getting the same delta on my E4300 on a DS3. Because of the way the socket 775 mounting pins work, the heatsink felt a little "looser" than I'm used to. So, when I reseated, I used a little more thermal interface goop, and now I don't go above 62C (OCd 8x375) with my Scythe Ninja.

Thanks, I'll do this tonight. This was my first time building a rig, so I may not have the HS completely flat on the CPU.

I originally applied the goop by spreading a thin layer on the bottom of the HS, then wiping it off (per the Zalman manual), then I made a small, vertical line on the top of the CPU...should I still go with the same routine? Or was applying it to both the HS and CPU too much?

On another note, I did notice at the time I screwed the HS down onto my DS3 that it required a good amount of elbow grease, but again, I wasn't sure if it was normal or not...

I spread an even layer across the entire CPU, about as thick as card stock, or masking tape. Also, I am using Shin-Etsu X23 thermal grease.

grain of rice in the middle shoud do you and those temps do look prett high for a 4400

I think your problem is either tat reporting to high temps (it is true if your cpu is one of the L2 stepping like mine) OR did you see your voltage is too high ? it should sit at 1.325v not 1.425v when at stock frequency.

The 1.425v is what I'm using now at 3.2ghz. IIR, at stock voltages/frequency, my temps were ~32C idle and ~52C load.

I have been having rather inaccurate temp readings since the beginning...including a ~15C CPU temp (BIOS and SpeedFan, Temp 2) in a room with a 22C ambient temp! Using CoreTemp .94, for example, had my Tjunction at or below ambient temp!

So, I had to offset Tcase (as noted above) and Tjunction in SpeedFan just to make the numbers match up with TAT. Still, after offsetting so many values, after a while, your head starts to spin and you don't remember which way is up

Update: Well, I ended up reseating my HSF about three times, but didn't see any concrete difference in temps.

I rolled back to stock voltages and clock speed, and temps were idle, ~33C, and at 100% load in TAT, ~50C.

So, I ended up reducing my overclock to 3.06ghz (and vcore down to 1.375), and now my temps are ~39C idle and ~65C load.

Better, still a high delta, but better...

I also resat the HSF outside of the case to initially check temps, so I know it's not a ventilation issue, because the 30C+ delta still occurred at 3.2ghz.

excuse me for my newbieness, but what does "delta" means and "load delta" "high delta temps" mean? 🙁, i have a e4300 runnin @ the same temps exactly, with 1.375 @ 3.02GHZ, and i have the same cpu and i reseated twice as u did lol =)

You're generally not supposed to have more than ~25C increase from idle to load. However, with the E4300 (or at least ours ), maybe that is a bit of an underestimation.

i'll tell you the batch of my e4300 as soon as i get home maybe they were made the same week hehee , im at work usin radmin lol 😉
