Computer heating and very noisy after new GPU

[Proximo1945]

Hi!

Two days ago i bought a new Sapphire R9 290 Tri-x . When i started a game (Assassin's Creed 4 for example) i noticed that after 2 minutes the computer became very noisy, like it's making a great effort to function. I thought it was the GPU making the noise but the readings on MSI Afterburner showed that the GPU fan went from about 24% when not playing a game and no noise at all from the computer to about 30% when playing a game and a very noisy computer, so it's hard to believe that those 6% are making the noise difference.
I downloaded Speedfan and got these readings during idle and during playing AC4:
Idle:

AC4:

I noticed that Fan1 is working 1000 RPM more when playing AC4 so i thought maybe that's what's making the noise. Then i made the computer work without involving the GPU by installing some software and noticed that the temp readings are almost as high as when playing AC4, and Fan1 went to about 2000 but the noise was no way near as when playing AC4. Also it's worth mentioning that before a bought the new GPU i had an hd 5770 and had no noise problems at all.
My questions are:
1. Are my temp readings, especially when playing games, to high?
2. Is Fan1 the cause of the noise, and what can i do about this problem?

Thanks in advance!

your GPU temps are okay, but your CPU is a bit high. Try to re-seat the CPU cooler or reapply the thermal paste. Or just open your side panel, find the most noisy fans and start troubleshooting from there

Because your GPU is strongly bottlenecking your processor, causing it to have to work harder to keep up with the GPU.

The Core i7 you have is an extremely old one, the Sandy Bridge series from way back in 2005. This graphics card, the R9 290X, is one of the fastest graphics cards in the world. When you pair an extremely old and slow processor with a new and extremely fast graphics card, the slower partner in the pair has to try and keep up with the faster partner to do his end of the work. That's what's going on right here. While the processor is working harder to try and keep up, it's creating more heat, which is turning up the heatsink fan (and maybe the case fans too, not sure). That's why it's so loud and hot

Hope I explained it clearly

Thanks for the quick replies.
I think the most noisy fan is a big fan on the top and back side of the computer.
I pondered before purchasing the R9 290 whether to buy a new computer or just a new GPU, so i asked on several forums, including this one (http://www.tomshardware.com/answers/id-2157751/upgrade-buy-gaming.html), if my i7 930 would suffice to function properly with the R9 290 and i got positive responses. The performance so far is very good, i can run the most demanding games on ultra settings more or less with decent frame rates, the only problems are the noise and the fear that my CPU will overheat.
Also i noticed now that on the next 30 seconds or so after i exit a game, FAN1 is dropping from about 2200 RPM to about 1150 RPM but the noise continues to be at max for that period of time and it starts reducing from a starting point of 1150 RPM, so maybe it's not this fan that's making the noise.

I dont know why they'd say that. The Sandy Bridge is old as heck. It's fast but not as fast as to keep up with the R9 290. It'd need some serious overclocking to do that.

i7 920 is NOT sandy bridge. it's nehalem. Sandy bridge is still OK for gaming. But nehalem is old by now and the cause of the bottleneck on your system

I checked and found that my i7 930 is indeed nehalem and it was released in 2010:

Anyway i think there are 2 different problems because i noticed that even when i disable my GPU and make the CPU work a little (browsing the net for 1 minute), the CPU temp rises from 55 on idle to about 70 - the same temp i get when i play games, even for a long period of time. This fact makes me think that the CPU heating problem doesn't involve the GPU.
The second problem is the loud exertion noise coming from the computer, which reaches it's peak in about 1-2 minutes after i start a game, and start declining immediately after i exit a game. The usual suspect for the noise would be the GPU fans, but they were working on 30%, and i tried raising them manually to 40% (not during a game) and there was almost no noise at all.
The other suspect was Fan1. I managed to make FAN1 work on 2100 RPM with the GPU disabled - the same RPM of FAN1 when i play games, and again there was almost no noise.
The only thing i can think of is that the GPU requires much more electricity than anything else in the computer, and maybe the noise is coming from the Antec Neo Eco 620w PSU when playing games.
Does my theory make sense?

An update after i went to the computer store to fix the problems:
About the heating problem, they said that 70c temp for the CPU is normal and that i shouldn't worry about it.
About the noise problem, they checked the source of it and it's indeed the Antec Neo Eco 620w PSU. They showed me the official requirements for the R9 290 which included 750w PSU and told me that i need to replace mine. From the research i did before buying the R9 290 i understood the 620w would suffice for powering the GPU without special problems.
Do their answers make sense?

Right now if the CPU is hitting 70C or more for any reason you NEED to be worried: http://ark.intel.com/products/41447/Intel-Core-i7-930-Processor-8M-Cache-2_80-GHz-4_80-GTs-Intel-QPI new replacements are just about unavailable and even used ones may take some effort to track down and your motherboard is not compatible with anything else so if the CPU dies you're looking at a full CPU+MB+RAM and probably another Windows license unless you're happy sourcing a replacement through Craiglist or E-bay.
First you should remove and clean the CPU cooler, replacing the thermal grease with something like Arctic Silver, if you're unsure as to how to do this there is plenty of online tutorials just Google 'CPU cooler removal' or 'CPU thermal paste replacement.'
The installed power supply should be up to the job but some do make a bit of noise when loaded, as has been suggested your best option is to run the system with the side panel off and see (or hear) which fan or fans are making the noise.
What case is the system installed in, how many fans are installed and where are they? That R9 290 produces a lot of heat and good case ventilation is very important to prevent its heat from overheating other components.

Hi its not your cpu any i7 will do just fine its that damn card the R9 290 and 290x overheats like craze its kinda mandatory to install a watercooler for that card and get a gpu cooler will really help a lot and what case have u got u need one with good airflow and a few fans intake in the front and outtake in the back you will be fine then good luck.
