FX 8150 Temperatures. - Page 2

Dang them im running a bit hot. Even at stock settings my socket temp goes up to 57 in a prime run. Its a shame considering my cooling setup, I know its not amazing but i would have thought it would have given some decent OC headroom.

Edit: Also probably not important but socket temp idle is 39.

I have the Hyper 212 Evo as well as an 8120. I replaced the stock Evo fan with two Gentle typhoon AP-15s. Overclocked to 4.1 ghz I'm at 38 degrees idle. The hottest I get is 53-55 degrees while rendering, games run at around 45 or so. Still pretty high but it's not terrible.

The big problem I have is that I can't run OCCT or anything that'll put my cpu under full load. I believe at 3.9 I hit critical temps in two minutes. It's not a big deal because my cpu will never get that hot with normal use. Though I did just order myself a new case that should allow for some better airflow. I'll re-seat the cpu with some Antec Formula 7 as opposed to formula 6. Might be another degree or two change. Every little bit helps.

Dang i really need to find out what is causing me to run so hot. I wouldn't think that with 2 Ultra Kaze's (one of which i used to replace the stock 212 fan) and AS5 plus the EVO would give me half decent temps..

Well, let's look at what we can do to fix this.

1. Are you sure you applied your thermal paste properly? I applied twice before finding that a pea size drop right in the middle of the cpu, then letting the evo spread it out was proper for me to do.

2. Does your pc have proper airflow? Hugely overlooked, first off you want to make sure your fans are pushing air into the case, while any top fans and back fans pull the air out. Warm air will be produced, it will raise, and if it isn't expelled out the top it can sit around. How good is your case airflow? Do you have lots of cables in the way? That can disrupt it quite a bit. And make sure your push and pull configuration moves air towards the expelling fans, not back into the case for it to sit around.

3. Too powerful of fans can hurt, not help. When air moves over an object, if said air is moving too quickly it won't have time to actually grip onto said object and cool it. Not only that, but if you have two MEGA powerful fans, I'd certainly hope you have enough fans to pull all that air out of the case. Once again, proper air flow.

Thermal paste is good. Re did after a mess up on the initial install. Although maybe the third times the charm. After work I will consider redoing it again.

Airflow is good. I even did a cable managment overhaul before install just to be sure.

I removed the second ultra kaze from the 212 evo and replaced it with the stock fan again. No noticble difference in temps. Socket temps anyway. Core temps went up a bit but you guys say the socket temp is the one to worry about so...

Also am I getting that the general consensus is that this guide

http://www.overclock.net/t/1128821/amd-temp-information-and-guide

is not accurate?

Thanks again guys.

If airflow is good and thermal paste is set, not really much more you can do than invest in even better cooling solution. Honestly, I'm running 4.1ghz right now using the evo myself. It runs great, I can't do any stress testing cuz I'll overheat past the limit. Though when will my cpu ever be used 100% to the point that it'll heat up that much?

Either way I am investing in a better case. I'll report when I change out all the guts and get the new case set up. If I see improved temps then I'll be sure to mention it. I just don't believe that a mid tower can hold as well a temperature as a full tower. If it turns out to be correct, may want to think about a more spacious case solution.

Yeah let us know how it goes. Maybe i'll go for a bit of an OC myself. It will suck not ot know if its 24/7 stable due to fearing socket temps, but in games its never going to go that high anyway. Plus im constantly monitoring my system on a second monitor so if it ever goes into the danger zone i'll just shut her down.

I messages AMD with some very well pointed and direct questions. Im not gonna leave then alone till i get awnsers. lol Even if i have to call thier support daily. XD I will post ANY relevant info i can squeeze from them.

This is my response from AMD.... When asking about the thread i have linked to sereral times already.

Response and Service Request History:

That specific thread is one that I am all-too-familiar with, to say the least. I was the original tech who was talking with Bubba Hotepp, and you can see our e-mail correspondence on page 8. Basically, the guide there is somewhat misleading. Tctl is a ridiculously confusing temperature reading that indicates the "safe zone" and is used by the motherboard for calculations on when it should start powering down the CPU because things are too hot. The 61C reading is for TCase, which is the temperature inside the physical CPU. This will be a higher reading than the CPU reading, which is at Tjunction, where the CPU and motherboard meet. TCore (CPU Core temperature) is a mathematically derived temperature based on the temperature at Tjunction, with input from Tctl as well. It's not an official reading, as it is mathematically calculated, but is a closer representation than the CPU temp which is often found where the CPU and motherboard meet, which is almost always cooler than the CPU temperature internally.

I struggle to follow a bit so if anyone can dumb it down a bit i would greatly appreciate it. smile.gif

Hmmm. Well, if that's the case, then I don't think that we can overclock the FX chips. My stock temp for the chip on tcase under idle is already 40'c. How the hell are we suppose to play with it if it's based on the CPU temp. This is total suck!

i have the 8120 i recently too were not satisfied with temps. my idle was 29 most of the time which is good but the chip does get hot quick. I talked to amd the chip default vcore is from 1.15-1.412(turbo core) the mobo i had at the time was a m5a97, which i found out was ****ty for overclocking, not even recommened for an overclock and had bad phase after asking here on the forum. today i went to compusa to return the mobo and get the sabertooth 990fx and now i can run at 1.236 full load with a 20x mult. verything else set to auto execpt turbo core disabled and my memory voltage/timing and speed i set manually and just changed multi to 20x and i have been running prime95 for 3 hours and i am now only at 55c, on the other board at 3.6ghz i would reach 56c in mintues which is past my feel safe zone of 55c since 61c is the max for our chips before they throttle down to save your chip from death. Also the paste that came with my notua d14 is way better the as5 i have both and tested both much better results with nactua's paste
