Hi, thanks for taking the time to read this thread! I have a couple of questions, but I don't think they'll be hard to answer :)

So, on December 21st, I built my first computer, even though I don't technically have all my pieces because 2 were backordered and 1 was lost somewhere by CanadaPost and they're trying to find it.

I chose the i5-4690k for my CPU, because it was on sale and the reviews were good. I haven't bought a cooler yet, but I know that I will be getting a Corsair H80i in a couple of weeks. Despite running the stock cooler, I decided to OC it, just to see what the results would be in term of temperature. I decided not to run prime95 stress test until I get the cooler, since I don't want to damage the CPU, but I did record the temperature during a gaming session. I played GTA 5 for about 3 hours straight, half online and half solo with mods, while using CPUID to record the maximum temperature of the CPU and each core separately.

My first question is : The CPU clock rate moves between 4,307Mhz and 4,106Mhz (When the load gets bigger, it throttles down to the latter), does it make any difference when launching apps that are less demanding? I'm not entirely sure if I should simply cap it at 4,106 or if it makes a difference in performance (it doesn't seem to really affect the temperature since it throttles back down during heavy loads).

My second question is : After the 3hours session of GTA 5, CPUID indicated that the CPU itself reached a maximum temperature of 67C and the cores reached between 66 and 69 individually. I think the airflow in my case is quite good, but I wonder if I should remove the overclock until I get the cooler because those temperatures could damage the CPU? I know that in the small guide that came with the CPU, it says the temperature shouldn't go above 72.02C, but how accurate is that? Maybe I'm paranoid, but since I have no experience in computer builds, I don't want to take any chances.

Here's the list of parts that I bought (the pictures show the ones that I received) : http://ca.pcpartpicker.com/b/b2d6Mp

My third question is about my GPU. I did a Valley 1.0 Extreme HD pre-set benchmark to test out my GPU, and I was wondering how good/bad the results are. The GPU is an EVGA GTX970 SC ACX2.0 and it is running at +135Mhz on the core (1489Mhz) and +700Mhz on the memory (4207Mhz, 8400Mhz effective). The score was 2808, and according to EVGA precision's OSD, it went up to 50C and stayed perfectly stable for the rest of the test. How are those results?

My final question : on the Link to PC partpicker, the 2nd picture shows what the interior of the computer looks at this very moment, how is the cable management? Is it ok or should I work on it?
 

for the first question, that's okay when you run single core demanding tasks, the turbo boost throttles the core at 4.3GHz and when all cores demanding task then it runs at normal 4.1 GHz thats not at all a problem.
for the second question your cpu temperature is not that high as compared to the workload and the 70 degrees mark is for the longer lifespan of the processor, it can surely handle upto 90 degrees but that will reduce the life of the cpu, modern cpus have a feature that the system shuts down just before reaching the temperatue that could damage the cpu so don't worry, but yeah don,t OC it further and don't ron p95 until water cooler comes
and yeah finally towards the gpu, yeah the results are pleasing
and yeah the cables look okay.
