Fitting my CPU i bought of eBay today it is a

Intel Core 2 Quad Q8200

It is running around the 50-60C mark is this fine?

Yes, running 50 to 60c while doing something is fine. If that is the idle temperture than you are going to want to check your HSF (heatsink/fan) to make sure it is seated right. The tcase for the Intel® Core™ 2 Quad Q8200 is 71.4c (this is a nice number to try to stay under).

I saw it at 59C after i came of LoL (league of legend) it hasn't been higher

2 of the clips has snapped on the heat sink but it is secure as 1 clip on each corner works or should i consider getting a new one?

Yes, you need a new heatsink. $30 problem solved - http://www.newegg.com/Product/Product.aspx?Item=N82E168...

The hyper 212 is about the best price/performance HSF you can get. Cheaper, lower performance, higher cost, better performance but then you pay extra.

Also you should look at the individual core temperatures, not the single one.
Normally the individual cores will be higher and as IntelEnthusiast said you need to stay below 71 C!!!

If two of the Stock HSF clips are broken DO NOT operate until repaired/replaced as your core temps most likely are TOO HIGH!!.

To look at Core temps download and install CPUID HWMonitor.
http://www.cpuid.com/softwares/hwmonitor.html

IntelEnthusiast will probably disagree, but In my humble opinion the stock HSF is best left in the box to keep the box from blowing away - I never install the stock HSF. I may love the Intel CPU, but the Stock HSF is at the BOTTOM of the totom pole in terms of performance. If your room temp is in the low 20's then your CPU should be in the low 30's at Idle and under load upper 40s to mid 50's

downloaded the CPUID program

core #0
Value = 56 Min = 55 Max = 58

core #1
Value = 46 Min = 45 Max = 48

core #2
Value = 51 Min = 51 Max = 54

core #3
Value = 46 Min = 46 Max = 49

Are these good readings? I have ordered a new heatsink which should be here tomorrow aswell

For @ Idle there are high, If with prime 95 running = good
The 10 C max difference between cores is on stock HSF is normally uneven pressure or uneven spread of the HS coumpound. 5 C diff between the individual cores is quite common. Another variance between cores is if they are not evenly loaded.

Normally I run Prime95 for two reasons (1) verify cpu/memory stability and (2) to verify effectiveness of HSF at stock and espeacially if I've OC the CPU.

For stability verification need to run a min of 4 Hours, many leave it run for 8+ hours.
Checking temps: Temps will ramp up very quickly so for the first 15 Minutes need to watch closely. If at the end of 15 minutes temps are still at a comfort level, then check about once evey fifteen minutes utill you are sure that the cpu is not a "frying pan"

My I5-750 OCed to 3.2 GHz stays below 60 C and my I5-2500K OCed to 4.2 also stays below 60 C while running prime 95. Their Idle temps are in the 30s (This is for all cores).

Added: The HSF will determine the best method of appling the Thermal coumpond (Myself I use AS5). For the Hyper you need to insure that the void is filled ( just google installing the Hyper 212 for a youtube video). For the Flat bottom HSF (which is what I use) I put a "pea" size blob on the cpu and work it around with my finger (use a latex glove). so that it looks uniform. Then stick the HS on and Rotate it back-and forth (CW/CWW just a small amount) - BUT be sure not to left up and get an air bobble between the CPU and the HS.

currently downloading Prime95 now, Should i try this now or wait until tomorrow when i get my new heatsink? i bought this

I'd probably wait, but if you do run it with current HSF, then have HWMonitor open befor starting Prime 95. Monitor temps as you may reach high temps within 5 -> 10 min.
It would show you the diff between the stock and the NEW.

I think i will wait :) , thanks for your advice being a real help!.

Also with the new heatsink i'm getting it comes with cooler master thermal paste shall i use that? or shall i use the MX-2 i have bought?

The difference between most of the 3rd party thermal paste is only a few degress and normally not a real concern unless tring for a high OC. I'm not used either of them. You probably could google for a comparision between the diff brands. AS5 is popular (also what I normally use), but not really the best.

http://www.hardwaresecrets.com/article/Thermal-Compound...
As you can see NOT a big difference - The HSF and how well the thermal compound is applied are the 2 Important factors.

And here is MX2
http://www.hardwarecanucks.com/forum/hardware-canucks-r...

Do NOT use to compare the two as the tests are differrent.

They are fairly even i would say so i'll stick with my MX-2, Once i get my new heatsink fitted and it is still high temperature would would you suggest the problem is?

Well finally got my TX-3 installed with artic silver 5 paste and here are my readings

Value = 56 Min = 53 Max = 58

Value = 44 Min = 43 Max = 48

#2

They seem very similar not much difference. I have just installed it 5 minutes ago, What do you think?

The CPU's TDP is only 95W. My 140W Phenom II 955 doesn't get above 50C on air.

I would pull the HSF back off, clean it with 90% isopropyl alcohol. Remove the CPU, clean with 90% isopropyl alcohol.

Are the temps for idle, or under load. If Idle, try running prime95 and see what they go to - just Monitor closely and 15 min is all you need.

Also what is your room temperature?

These are results using Prime95, I used the Blend (Tests some of everything, Lots of RAM tested)

core #0
Value = 64 Min = 54 Max = 65

core #1
Value = 55 Min = 44 Max = 56

core #2
Value = 59 Min = 51 Max = 60

core #3
Value = 55 Min = 44 Max = 57


Has been running for more than 30 minutes and not hit over the 70c marker yet, Would you say this is fine?

I did this but only have 70%

I noticed that the thermal paste didn't spend well due to the groves so filled the grooves up with paste rubbed in with fingers then did another pea size blob on the CPU and getting the following readings above with Prime95

29C is pretty darn good on an air cooler as long as you didn't take that screenshot with the computer still cold. Run some stress tests in Windows and take some temp readings.

How come the readings on Speccy and CPUID GWMontior are coming up as in the 50-60 mark though but then go in BIOS it's on 29c

How do i run stress tests in windows? as i have used Prime95 and get maximum readings of 64c

I hate to tell you this, but Speccy and CPUID may be getting the wrong readings from your motherboard. It happens sometimes with software based temperature software. I would download whatever utility the mobo manufacturer has for temp reading.

Them readings were during Prime95 and using HWMonitor.

So my CPU Temp is 29c but all the cores are at 50-60c?

29C is the motherboard reporting, 50-60C is the CPU cores reporting. Typically you only see these figures differ by a few degrees, not 20-30C difference. Maybe someone with more experience with wonky thermal readings will chime in.

The diff is your 29 was in Bios (CPU Temp) CPU at nominal freq (Speed).
You then loaded windows, and at Idle your cores are ____. (prabably cose to 30.
Your 50-60 C were for CPU at nominal Freq (Speed) BUT LOADed close to 100% for all four cores. So YES they will be Much higher than bios cpu value.

Added: Generally core Temps @ Idle should be around +9 C above Ambient room temp.

I have watched a few videos and i'm going to use the 'Spreading technique' when i apply thermal paste to my CPU so it gets totally covered as i have pipes and could be causing it to not spread on the CPU, If this doesn't work i'm totally out of options ha

I've used speedfan before to watch my temperatures. The trick to the program is that the cpu temp that fluctuates the most is your cpu temp. So run a game and monitor which temp rises and cools the fastest and that's the cpu temp. Good Luck.

For speed fan, verify tjMax is correct, How does speed fan compare with HWMonitor. On My Z68 HWMonitor is good on the core temperaturs (Voltage were out of wack).

Didn't catch ambient (Room temp) for ever 1 C above room temp of 20 C expect about 1.5->2.0 C increase in Core temps.

PS I would not sweat a 68 C with Prime 95 unless planning to OC. Games will be lower.

I would be more inclined to believe the mobo temp readout (titled "CPU"). Like I said before, I think there is an incompatibility with temp software and your mobo. Otherwise, I would suspect the temp sensor in the CPU may be faulty. However, this is all purely speculation.

DON'T sweat the diff between individual cores and CPU. The temps sensors for the cores are located where the heat is being generated. The CPU sensor located much closer to the top of the CPU and benifits more from the HS.

What you need to do is confirm the reading of the core temps. ie try a couple of programs and see how they compare. There is an offset (tjMax) that if incorrectly applied will make a diff.
