Hi I just switched out my i5 2500k (per core 60 degree average) for an i7 3770 (per core 83 degree average), I have an old Cooler Master V8 CPU cooler and no case fans (the case is open). My question is, is this temperature acceptable for this CPU and will adding a fan case at the front and back of my case drop the temperatures? Thanks.

Edit: I just want to further add, I was rendering a video just then and the 3770 was at full load and the first four threads were hitting 95 degrees and the last four were hitting 90, then as soon as I cancelled the test the temperatures dropped to 50 degrees in around 3 seconds. I stopped it because it was getting very hot according to MSI Afterburner, does that sound normal?

The 3770 should theoretically produce less heat than the 2500K, so a core reading of 83C with a decent cooler like the V8 seems off to me. Is this at idle or at 100% load? What are you using to read the temperature?

I assume that when you swapped the CPU you reapplied thermal paste? If not, that's the most likely cause.

Yeah I reapplied the thermal paste, though it is not the same one that I had before, it's called Stars-612.

At right now it hits 90 degrees, idle is around 40-50.

I didn't know that the i7 should be generating less heat so I have no idea what the problem is.

I'm also using MSI afterburner to get the CPU temps, same as when I had my i5 2500k installed.

Yep I used the V8 on the 2500k, fan is spinning.

Should I get some Arctic 5 or whatever that is called?

Though when I touch both sides of the heatsink it isn't even warm!

And RealTemp has around the same temperatures as MSI Afterburner, at full load it is still at 90-95 degrees so I stopped rendering the video again because I don't want to destroy the 3770.

From the differences they are on the same level of heat the 2500K is a 95w TDP 4 core CPU with the heat spreader soldered onto the die, the 3770 is a 77w TDP 4 core CPU with the heat spreader not soldered but using thermal compound between the heat spreader and the CPU die.

Plus the 3770 has the additional capability of Hyper Threading and hyper threading adds heat, 90c is hotter than you should be running it keeping it below 80c would be much better, but you have to take your ambient into consideration and case air flow, your cooler is really old school and way behind the technology curve for performance cooling even though it looks impressive it never was King of the Hill, so to speak.

Keeping your 3770 cool is dependent on many factors and just because your side cover is off your case does not mean the CPU cooler is getting good needed air flow, plus you don't even mention what memory speed you are running, anything above 1600mhz is overclocking the CPU memory controller and also adding heat to the CPU.

I have a B75 chipset board so I cannot overclock RAM or CPU.

So I guess I need a new CPU cooler?

I live in Australia and the socket is pretty old so not many choices, here are a few would these be better or sufficient?

Some of the best thermal compound on the planet is still Artic Silver 5, even though it requires a cure in time once that cure in is complete it has bested other compounds as much as 5c in some situations.

The best thermal conductive element in the periodic table is silver and Artic Silver 5 does contain silver.

Don't take my word for it check it yourself, that's what Google does best. :)

Sadly not, I have a B75 chipset mobo so I can't overclock the RAM or CPU.

4Ryan6 stated my cooler is getting rather old would you be able to look at the CPU coolers on my reply to assess if they are a better choice? Thanks.

The v8 is still a good cooler mate , if you're hitting 90c & the sink metal is cold its fairly certain that heat is not being transferred to the cooler properly.
Whether that's down to poor paste quality or application or whether the internal compound in the CPU is failing is the million dollar question here.

Not really recommended by most but have you tried physically stopping the fan spinning under load to see if the sink heats up dramatically with no airflow.?

Saying that your old temps on your i5 are higher than I'd expect too - I wouldn't expect it to hit much above 50c with that cooler under heavy load .

I'm going to assume in oz that your ambient temps are well in the 30's??
That's going to affect load temps quite drastically.

OK, if there's no previous overclock then I'm with madmatt30 in that heat isn't being transferred to the heatsink, so some better thermal paste would be the first thing to try. Also check that the cooler is mounted correctly.

I use Arctic Cooling MX-4 and highly recommend it, but Arctic Silver 5 will do just fine.

Yeah earlier today was when it was hitting the low to mid 90s and it was 30 today. Right now it is 20 and playing GTA 5 with a lot of CPU intensive mods around 70-80% load brings it to mid to high 80s.

I did buy the i7 3770 for $230 used. Which I would consider a great boost in performance when I can resell my i5 2500k for $100-$150.

The fins are cold on the V8, heatpipes are warm-hot and the CPU fan is pushing out air at or close to its maximum I would say.

And I'm going to try the stopping the fan trick in a second, and your thoughts on the Noctua D-15?

Thanks.

Alright thanks, I will order some now and this was my first time replacing a CPU as I bought the system used too but it was a great price and works great. I wouldn't call myself a novice but I'm almost 100 percent sure that I put the V8 back on correctly, though I don't really have faith in the thermal paste that I have applied to be completely honest.

I'd expect 50c max over ambient with that cooler at 100% load mate so something is off - you're essentially getting temps 20c+ over what they should be.
The noctua is a good cooler but not massively superior to your current one.

& honestly with a CPU hitting 90c your heatpipes should be skin burning hot not just warm

I just ran GTA V with very heavy mods again, it hit high 80s again and the V8 was actually hot. I think it's both the thermal paste and the V8. Thanks for the help I will buy that Noctua D-15 that 4Ryan6 suggested because I think the V8 could be the main issue here.
