1090T temperatures too high?

[DemiGoth]

I have recently changed motherboard because the old one was dieing. The new one (AsRock 990FX Eextreme3) works fine with my Phenom 1090T, but I'm a bit worried about the temperatures though.

From an other thread I learned how to read the values in HWMonitor.

I am a bit concerned about the temperatures displayed and certainly when I compare them to the calues of my old motherboard (ASUS M4N72-E). The main increase in temperature on my board is on the CPUTIN where on the old motherboard it would hit 62 at 100% load for 15 minutes and the above image it's a load at around 75% for half an hour. And when I compare them to the core temperatures, those are about what they were.

At this moment I haven't overclocked the 1090T but I am thinking about it. I am using the CoolerMaster EVO3 air cooler and did apply new paste. I am wondering if the values shown by HWMonitor are accurate or that I should change the cooler for the Corsair H55 hydro cooler. I can also add an extra air fan (on the case lid) just above the CPU for better airflow as option as well.

Any input and advice is welcome!

Do your CPU temperatures get that high during real normal loads? Probably not. If your computer's main purpose is to run prime95 24 hours per day, then you might want to get some air conditioning and perhaps a better cooler.

The [strike]Corsair[/strike] Fisher Price H55 will not cool that chip.

Thanks for the quick answer Damric and the comment on the Fisher Price cooler 😀

Normal load temperatures on the picture in my OP are the one for the active value. I happen to have an extra case fan, and my computer case allows up to 2 fans on the case side lid, and I applied the fan on it just above the CPU. Here's a new pic with 10 minutes of Prime95 running:

Needless to say that adding that one fan has quite an effect on cooling, more than I eevn expected. I like it that the core temperatures have dropped 7C each! Also worth to note that after closing down Prime95, the core temperatures dropped back to normal values within a minute, and the CPUTIN took a bit longer (around 5 minutes).

Question remains, if the temperature now 'low enough' to start thinking of overclocking that old CPU, of do I need to look for an other cooler if I want to get the best performance out of it. If so, which cooler would you recommend?

Extreme 3 has inferior VRM design. I wouldn't push it too far. If I recall from my old 1090T, it was 3.2GHz base with 3.6GHz turbo. To avoid high thermals but still get some extra MHz, you could tweak your Turbo higher. You can do that in AMD Overdrive or perhaps also with PhenomMSRTweaker (if you can find that program). It takes a big boy motherboard and a big boy cooler to clock the old Thuban very high, so it's not really worth your $ to try and push it far with straight overclock. But if you really want to drop some dough, let me know and I'll recommend you a few models.

Just bought the motherboard and I don't want to spend too much at this moment on hardware because of the crisis and such (dropped 40% in income over the last 5 years...). I bought the Extreme3 as a quick and cheap replacement for the old one that died while keeping my SLI up & running. If I would be able to overclock with it, than I'm okay, but with the old CPU on it I think I'll pass and wait for better times to build a monster

Just try tweaking the turbo, that way you aren't stressing the motherboard VRMs so much. It will generate less heat with normal loads than standard overclocking as well.
