SHORT VERSION: I know that Haswell CPU's tend to run on the hotter side but is 92C normal for 100% load?
LONG VERSION: I'm worried my CPU may be much hotter then what is recommended. using HWmonitor to watch my CPU as i ran Prime95 I saw that after a few hours at 100% load the temperature reached a max of 92C(197f). I'm not sure if this is normal for Haswell CPU's. As im typing this, the temperature is currently reading 38C(the only applications i have open currently are opera and HWmonitor).
CURRENT COOLING SETUP: My cooling setup is a stock intel fan that comes with most intel CPU's and im using arctic silver for my thermal compound. I also have 3 120mm case fans. my room temp is usually at 23C(73F)
1. Do NOT use Prime95 with a Haswell CPU. That synthetic benchmark is old, and meant to be used on older hardware running older instruction sets. Even after "updates", Prime95 is not appropriate for these newer CPUs.
2. Do NOT overclock or stress the CPU whilst using the stock fan.
Depending on how long you let the test run, you've probably drastically reduced the longevity of the CPU. If you ran it briefly, it shouldn't have caused too much to be concerned about.
I also had bad temperature problems which were mostly because of bad thermal paste appliance, but check out my thread on my even hotter 4770. I'm afraid the stock cooler is just shit, you can get very good coolers cheap now, or if you have an older intel build, get the bulkier cooler you find from core2duo 65nm and below. As a matter of fact haswell coolers are even thinner than a 2007 core 2 duo cooler, which is retarded since they get hotter.
It's not as simple as that, you can't be certain of the cpu's lifespan. It might fail soon, it might never (anytime soon) fail even after a torture test.
I never said I was certain of the CPU lifespan. I think you need to re-read the entirety of my post and what I was trying to say. He may or may not have reduced the CPU lifespan. If he ran the test for a long time, then the chances of damage are incredibly high.
Intel's not a big company or anything, and they have super reasonable prices. So it's only understandable and perfectly reasonable they cut prices any way they can, including having a cooler that isn't sufficient for the CPU at stock speeds.
thanks for the answers guys. sounds like i need to check my thermal paste application or most likely buy an after market cooling solution. but now Berserker has me worried that i may have damaged my CPU.
Prices are actually much lower than in the past. A mainstream dual core used to be 350$ (E8400). A mainstream quad core used to be Q6600, (initially a 800$ chip) ~500$. An i7 today is ~350$ while the equivalent dual core in 2007 (the e8400 of today) is a 3570k at 200$
Seems their prices are higher than they were in Sandy Bridge and Ivy Bridge. 4670K now is $240-250, while the 2500K and 3570K were $220. The 3770K was $320 while now it's $350 for the 4770K (and the older gens' prices have gone up with it post-Haswell).
