A10 7850 runs Hot!

Just built mITX system, Gigabyte F2A88XN-WIFI, AMD A10 7850K with stock CPU cooler, tucked in a RAidmax ITX-0907-BP case (with 3 80mm case fans), running Windows 8.1 Pro. The CPU runs hot, 60 to 70 c at idle; when recording with Windows Media Center, temperatures reach 93 c. When I close WMC, temp drops to 60-70 c again. No room for larger CPU cooler, I moved the MB/CPU to Antec ISK 600 case (120mm case fan); still runs Hot! Installed GELID SlimHero 120mm/4 heatpipes CPU Cooler. CPU still runs Hot. Using Speccy to monitor CPU temp, under light load CPU temp ranges from 70's to low 90's. I tested running WMC, Speccy, and MCEBuddy2; let it run for 30 minutes and watched CPU temp climb to 110 C! Had to shut it down. I found a closed thread for similar A10 7850k overheating issue, but did not see where it was resolved. Suggestions, Please

 

I used Arctic Silver Ceramique 2 compound; was getting same behavior with AMD stock CPU cooler (that came already attached to the CPU). I agree, it behaves as if its a thermal transfer to the CPU cooler problem. I ran a 1 hour test this morning, with CPU load ranging from 50% to 100%, CPU temp hovered between 89 C to 93 C. When I removed the load (to 8-15%), the CPU temp dropped the quickly to 58 C to 69 C. btw, the 120 mm case fan, i set to high speed; also, fyi, I using 500 watt 80 Gold power supply which has a 120 mm fan. So case temperatures are normal. I'd appreciate any suggestions. drdelp

 

Only slight temperature difference with case cover removed (now that I have case fan running on high). I am using Piriform Speccy to monitor temperatures, and I wonder if it might be Speccy itself, because the GPU/graphics are integrated in the A10 chip, Speccy shows a very different temperature for the CPU (88 C) and the GPU ( 33 C). I downloaded and installed MajorGeeks Core_Temp_1_rc6 and it shows CPU#0 at 35 C; I'm wondering, is Core_Temp reading the GPU temp or the CPU temp? And is Speccy mis-reading the two temperatures. Maybe one is real and the other is bogus?? Any suggestions for a 3rd program to monitor UEFI based system temperatures?? Thanks, again, drdelp

 

I may have the answer; it might be a Speccy issue. I used a hand held infrared thermometer and shot it at the base of the CPU cooler; readings were 41-45 C (+/- 3% spec of the infrared gun). Within 1-2 degrees as to what Speccy was reporting for the Graphics Processor Unit (while showing 91 C for the CPU.) I went on Piriform forum and there is a post about Speccy misreading temperatures on AMD A6, A10 etc (although I don't see any posts or reply's to this one post...) drdelp

 

Thanks for your feedback, I'll give Core Temp and others a try. And thank you for responding to my post; it's good to get another perspective on the problem! At least now, I won't be worrying about frying my CPU! Have a great day! drdelp

 

Update...Speccy may be reading temperatures correctly. I made the leap to switch from air cooling to liquid cooling; changing out the 120mm low profile cooler for a Corsair H55 Liquid CPU cooler. The A10 7850k still runs fairly warm at 76-78 C under full load (97 to 100% load on all 4 cores), with the GPU cores of the A10 running at 27-28C. My conclusion is the A10 7850k runs HOT under load. For comparison, on another machine, I am running an older I7-2600K (LGA1155), air cooled; Speccy reports its temperature at 72C to 82C, depending upon load (80+%.) I'd appreciate feedback on anybody with an A10 7850k. Many thanks. drdelp

 

Hi, I read this forum but never post, signed up today after I read your issue with the APU. I have an A10-6800k , runs similarly 'warm'. Basically, the cooling fans supplied with these APUs are not good at all.

There is an option you could try for better cooling. Go into your bios and disable turbocore technology. It sounds like a good feature, but it produces a lot of heat on the APU due to auto clocking. Also be sure that AMD cool n quiet is set to enabled and not just auto. You really will not lose much in the way of processing power with those settings.

As far as temperature sensing, use AMD overdrive for that. Specifically, be sure to look at your thermal margin in the cpu window. The higher that number, the cooler your APU is running. These are amazing chips but they do generate a lot of heat when not using a separate gpu. Hope this helped.
