Installed new CPU Fan, RPM too low?

So I have been experiencing significant stutters when I play some games, and it seemed to be that my CPU was getting to hot (around 74C) so I bought a Thermaltake Frio Silent 12 as it was in my price range and I figured it would be better than the stock cooler.

Temperatures have dropped a bit, down to around 62C, however I'm still getting the stutters. When I look at the "Fan #2" RPM, it says 468rpm, which is a little low I think?

How do I increase this?

My full rig is:
CPU: i5 2500 3.3GHz
GPU: GTX 780
RAM: 8gb
PSU: Thermaltake Litepower 700

If anyone thinks the problem could be elsewhere please let me know, I've already downloaded afterburner to lower my GPU temps also!

Thanks!

What are your GPU temps? Those temps for CPU are not very high and should not impact your gaming.

Try opening Task Manager to see if your CPU is being maxed while gaming. We need to eliminate/identify the CPU as the cause.

The fan speed will be controlled by your MB in order to manage temps. If the temps are low the fan will spin slower, so nothing to worry about.

there was no problem with 74C, if it's cool I would not be concerned about the fan speed.
As for stutters:
Using afterburner and other tools.
How much vram are you using?
Is your GPU clock speed constant?
what is your GPU utilisation?
What is your CPU utilisation and clockspeed?
What you you RAM utilisation?

My bet would be using pagefile instead of RAM.

My GPU temps WERE getting to 80C, and with afterburner they get to 66C.
I did some research and I thought that 74C was way too hot for a processor? It certainly seemed to match up with the stutters ie. at the start of games it wouldnt stutter (when the CPU was cooler) and as a match progressed and the CPU heated up it would get bad.

Can you explain all of this better, I don't have a ton of PC knowledge.

As for stutters:
How much vram are you using? In Afterburner it will indicate if your GPU memory is being maxed out. You have 3GB and some games might use all of it.
Is your GPU clock speed constant? Afterburner can give you a graph of your GPU clock speed. If your clock speed drops a lot then your GPU may have issues.
what is your GPU utilisation? Again, Afterburner will be able to indicate if your GPU processor is being maxed out.
What is your CPU utilisation and clockspeed? Afterburner can monitor this also, but task manager is quicker.
What you you RAM utilisation? Your PC has 8gb ram, is it being maxed out while gaming? Both Afterburner and Task Manager can monitor this.

So basically you need to use Afterburner to identify any performance issues on your PC which can help us/you identify the cause of the stutters. The CPU/GPU temps are not the cause.

Okay thank you, is the easiest way to do this to run a benchmark?

Edit: Nevermind I worked it out, will post figures soon

How much vram are you using? I believe it was using all of it
Is your GPU clock speed constant? Yeah, at 1006MHz?
what is your GPU utilisation? Around 80%
What is your CPU utilisation and clockspeed? Around 50-70%, 3005MHz (I don't know if that's the right value)
What you you RAM utilisation? 5 gigs-ish

You said the GPU/CPU temps aren't the problem, but I was experiencing much worse stutters before I lowered my GPU temp.

The problem is those temps are totally within the margins of both the CPU and GPU, so they should not have an impact on performance at all. For example, I am running a GTX580, a much older card than yours, and my temps are often in the low 80s for extended gaming sessions and it never impacts my gaming in any way. If you go and read reviews/benchmarks you will notice that most GPUs (even the newest ones) often hover around the low 80s and this does not impact performance. Only once you start going above 85 does the GPU start throttling.

Do you experience these stutters in all your games, or only in some? Have this always been the case or is it a recent development? Does some of your games ever crash out or even cause a total reboot?

Right now I am thinking 2 things, either driver/windows updates, or PSU issues. However, answer the above first then we can move on to more tests.

I did just notice a dip in the GPU clock speed which occurred at the same time as the stutter. That must be it I guess.

It was ever since I installed the GTX 780 (upgraded from a GTX 560) and upped the settings in my games. It happens the worst in Evolve, however happens to some degree in most games.

Edit: No game ever flat out crashes, no.

Did you get the GTX 780 new, or used? If the GPU temps are low then it should not throttle, so the stutter/clock speed dip is weird. You do have the latest drivers installed I assume.

Without another PSU to test it is difficult to say. Since it only started after you got the 780 we know it is either the GPU or the PSU. Can you borrow a PSU from a friend to test in your system?

I got the GPU used, but it looked like it was in good condition.
Unfortunately I don't have any friends who play on PC, I guess I'll just have to buy a new PSU whenever I find the money!

Could it have anything to do with the RAM at higher graphics settings? The guy who built the PC put 4 sticks of RAM in, and some are bigger than others?

So I guess I have 4x2gb, could this potentially be the cause as I've gone from low graphics settings to very high?

Your GPU will always be hot to the touch. Be careful touching it, not only can you burn yourself, but you can introduce static into your system which can potentially damage your components.

99% GPU usage is fine, how is the performance, does it still stutter?

The physical size of the memory modules does not reflect its performance. You need to know what exact memory is installed. The easiest would be to simply run CPU-Z http://www.cpuid.com/softwares/cpu-z.html . It will tell you the ram frequencies and latency. If the modules are not identical then it is not ideal.

In regards to the RAM frequencies and latency, where do I look on CPU-Z to find this?
