I'd like to preface this by saying my knowledge of computers is fairly limited. I've put together a computer before by following step by step instructions. For the most part, including the PC I am writing about, I have a friend help build for me.
I recently upgraded my computer's CPU and Motherboard to an Intel i7 4790K and the ASUS Maximus VII Hero. I also changed my CPU fan to the Corsair H100i. My question involves the i7 4790K's temperature readings. Most commentators recommended RMA, but some of those still had the same issues after RMA. I've found a few posts and comments on various forums, this one included, that noted that Intel has claimed that most programs are unable to accurately assess the i7 4790K's true core temperatures. And I'm hoping to see if anyone can either share with me a source or a similar experience to confirm that what I am experiencing (described below) is not an actual, functional issue.
After I upgraded to the CPU, mobo, and fan, I did not notice any functional problems. It ran and continues to run amazingly well. However, the reason for my upgrade was because my 13-month old Antec Kuhler 650 stopped working and fried my old CPU. So I've become a little paranoid about temperature. I installed Dragon Age Inquisition and played for about an hour. Not a single ounce of a problem- completely smooth, flawless, no lag, or any other concerns. However, before I exited, I figured I'd give RealTemp 3.70 a look to see the temperature and, to my surprise, all cores were listed in the 90's and apparently had been sitting there for probably the entire time (based on the timestamp for maximum temp).
Naturally, I started freaking out a bit trying to figure out what the problem was. Across my hours of Google searches, I came across varying stories of recent bad batches of the i7 4790K or other people posting about cheap components. But a small strain of posts described my scenario perfectly (like http://www.tomshardware.com/answers/id-2375114/corsair-h100-4790k-bad-temp-reading.html). Although RealTemp immediately reports drastically higher temperatures when under load and my CPU fan immediately kicks into overdrive, nothing else actually happens.
I ran two tests. First, I opened up my tower while the PC was running. I loaded up Dragon Age with Real Temp up. Immediately the temperature jumps from the high 30's to the 90's and up. However, my well-secured CPU fan is blowing cold air. It was still blowing cold air after 5 minutes, 10 minutes, 20 minutes, and even 30 minutes. All the while, I had no problems with the computer lagging even a fraction of a second. And previously when I was playing for an hour, I also had zero issues.
Next, I downloaded SpeedFan 4.50 and opened both Real Temp 3.70 and SpeedFan 4.50 to compare. At idle, Real Temp reported 39, 37, 38, 37 C temperatures @ Load <1%. SpeedFan reported CPU 37 C with 2012 RPM CPU fan, 670 RPM Aux Fan, and 959 RPM Aux 2 Fan. Sure enough, when I opened Dragon Age, Real Temp's numbers spiked to 95, 96, 98, 90 @ 54% load. However, Speedfan reported CPU 54 C. The CPU Fan, Aux Fan, and Aux2 Fan increased to 2818 RPM, 918 RPM, and 2642 RPM, respectively. The remaining increases for SpeedFan, if any, were negligible. SpeedFan also did note a change in the VcoreRef-Vin4 value from 0.35V to 0.62 V. None of the other Vcore values changed.
A lot of the posts I've seen have quickly dismissed SpeedFan's results over Real Temp's. Unfortunately for me, SpeedFan's results are the only ones that make sense. Any help in confirming or pointing me in the right direction would be greatly appreciated!
