Case: HAF 922
Heatsink: cooler master hyper 212+
cooling: stock on case+ dual sff21fs on the side panel
two sff21fs in push/pull on the cooler

hardware:
i5 750 @[strike] stock vcore[/strike] EDIT: it's 1.216v 100% load and stock frequency
5850 black edition

so I added the sff21fs and also replaced the AS5 with gelid gc-extreme (I cleaned the cpu and bottom of heatsink with isopopyl 91% q-tips and coffee filters before application) and my temps mysteriously climbed about 5 degrees C on CPU and GPU and ambients remained unchanged so is this just an incorrect TIM application? I used the uncooked grain of rice method, should I try the line method? Should I wait for it to cure?

thanks, just a bit puzzled here any help would be appreciated

Ask if you want more info

and lastly I always select best answers

I'd work on your CPU voltage; adding voltage to your processor is what makes it hot in conjunction with higher clocks. If you can lower your volts to something stable, yet keep your OC, you will see lower temps. Dig through OC sections on this and other forums...it's very, very likely someone has some exact BIOS settings for your chip to help you get close to what you want to accomplish.

I have a fan controller attached to both 200mm, and all sff21fs so i can do experimentation easily with those fans. I think that I have slightly positive air flow. my side panel s-flexs are running slower than usual and my 200mm intake is also slowed down in an effort to attain neutral airflow

If anyone is puzzled to why I'm running my CPU at a higher voltage than necessary is because I never changed it back after a failed overclocking adventure and all my temps are below 60 C full load so I'm not worried ideally I would like my temps under 40 C load since the room is 18 C

temps 100 % load max w/upgrade

Core 0: 57 C
Core 1: 57 C
Core 2: 57 C
Core 3: 55 C
(at least the paste is even)
GPU: 29 C (this temp is idle) fan 35%

CPU temps before upgrade
Core 0: 51 C
Core 1: 51 C
Core 2: 53 C
Core 3: 48 C
less even but cooler

1. Are your temps before/after both with the same OC applied?
2. How much TIM did you use during application? You want something that is a grain of rice or smaller.
3. Negative case air pressure is better; you'd rather have more air pushed out than forced in. Move your highest CFM fans to your back/top to get more air out; install the other, slower fans to pull air in.

I'd reset your OC back to base BIOS stock settings, see what your load temps are, then go from there. It sounds more like some bad OC settings in your BIOS...
I'm running my CPU at a higher voltage than necessary

I'd do some more research and see what are expected voltages for OC's on your chip, but again, when you don't know for sure what's causing the heat issues, remove overclocking as a variable and revert to stock until you get your fans and cooler figured out.

1. I am running at stock frequencies with a bit higher core voltage than necessary and before/after temps are with the same settings
2. I applied uncooked grain of rice
3. What config do you suggest here are all the fans I have available:
Scythe s-flex sff21f x4
200mm cooler master x2
120mm stock back exhaust fan cooler master x1
120mm blademaster x1

I'm not overclocking the reason I'm running at a higher core voltage than necessary is because I tried overclocking before and failed so restored stock frequency just not voltage, I don't want to go back to stock voltage because I plan to overclock very soon and before and after temps are with the same core voltage so that is what I'm comparing

If this is unclear just ask me to clarify the muddy parts

my cpu idles with 1.248v and when under load is less ~1.216v does this have something to do with disabling the power saving functions?

do you think that I should remove the rear exhaust because I have push/pull on my hyper 212+

What are you using to view these settings? Are you setting your overclock in BIOS or a GUI application?

Leave rear exhaust fans. Your case airflow should be:
Front: intake
Side panel: intake
Rear: exhaust
Top: Exhaust

Some cases have bottom fans, these would also be intake; warm air rises and all ATX/BTX case designs use the low to high, front to back airflow design.

You could add another fan in there if you wanted, it would only help. Just seems odd that you would use the same cooler, only different TIM and get those temps. Are you sure you are making good contact?

Did you add new fans to the cooler? Which direction are they both running...you mentioned push/pull...are they both pushing air the same direction for sure? Both should be:

<-fan | <- cooler <-| <-fan

I overclocked to 3.6ghz 1.3v and my temps are just under 70 C, it's winter here (ambient in house is 18 C) so I need to find out how to keep the temps around there for summer (it reaches 32 C in house, summer)

I'm thinking about getting a [strike]scythe ap-30 http://www.svc.com/d1225c12b9ap-30.html[/strike] EDIT* Changed my mind want to get this delta-> http://www.svc.com/afb1212hhe-f00.html and a pci slot cooler to get my case airflow evened out or just a bit negative.

Yeah, I'll try to get that vcore I'm following the i5 750 guide on this forum and the specified suggested vcore ended in a failure to boot so I had to push it up to this, and hopefully my gelid gc-extreme will cure a bit more in the next few days.

I'm also gonna mess around with my fans, thanks for all your help
